### Example Question #74 : Geometry

Find the surface area of a non-cubic prism with the following measurements:

**Possible Answers:**

**Correct answer:**

The surface area of a non-cubic prism can be determined using the equation:

### Example Question #1 : Solid Geometry

The above diagram shows a rectangular solid. The shaded side is a square. In terms of , give the surface area of the box.

**Possible Answers:**

**Correct answer:**

A square has four sides of equal length, as seen in the diagram below.

All six sides are rectangles, so their areas are equal to the products of their dimensions:

Top, bottom, front, back (four surfaces):

Left, right (two surfaces):

The total surface area:

### Example Question #2 : Solid Geometry

A rectangular prism has a width of 3 inches, a length of 6 inches, and a height triple its length. Find the volume of the prism.

**Possible Answers:**

**Correct answer:**

A rectangular prism has a width of 3 inches, a length of 6 inches, and a height triple its length. Find the volume of the prism.

Find the volume of a rectangular prism via the following:

Where l, w, and h are the length width and height, respectively.

We know our length and width, and we are told that our height is triple the length, so...

Now that we have all our measurements, plug them in and solve:

### Example Question #21 : Solve Problems Involving Area, Volume And Surface Area Of Two And Three Dimensional Objects: Ccss.Math.Content.7.G.B.6

The above diagram shows a rectangular solid. The shaded side is a square. In terms of , give the volume of the box.

**Possible Answers:**

**Correct answer:**

A square has four sides of equal length, as seen in the diagram below.

The volume of the solid is equal to the product of its length, width, and height, as follows:

.

### Example Question #1 : Solid Geometry

A pyramid has height 4 feet. Its base is a square with sidelength 3 feet. Give its volume in cubic inches.

**Possible Answers:**

**Correct answer:**

Convert each measurement from inches to feet by multiplying it by 12:

Height: 4 feet = inches

Sidelength of the base: 3 feet = inches

The volume of a pyramid is

Since the base is a square, we can replace :

Substitute

The pyramid has volume 20,736 cubic inches.

### Example Question #321 : Geometry

A foot tall pyramid has a square base measuring feet on each side. What is the volume of the pyramid?

**Possible Answers:**

**Correct answer:**

In order to find the area of a triangle, we use the formula . In this case, since the base is a square, we can replace with , so our formula for volume is .

Since the length of each side of the base is feet, we can substitute it in for .

We also know that the height is feet, so we can substitute that in for .

This gives us an answer of .

It is important to remember that volume is expressed in units cubed.

### Example Question #2 : Solid Geometry

The height of a right pyramid is feet. Its base is a square with sidelength feet. Give its volume in cubic inches.

**Possible Answers:**

**Correct answer:**

Convert each of the measurements from feet to inches by multiplying by .

Height: inches

Sidelength of base: inches

The base of the pyramid has area

square inches.

Substitute into the volume formula:

cubic inches

### Example Question #1 : Pyramids

The height of a right pyramid is inches. Its base is a square with sidelength inches. Give its volume in cubic feet.

**Possible Answers:**

**Correct answer:**

Convert each of the measurements from inches to feet by dividing by .

Height: feet

Sidelength: feet

The base of the pyramid has area

square feet.

Substitute into the volume formula:

cubic feet

### Example Question #321 : Isee Upper Level (Grades 9 12) Mathematics Achievement

The height of a right pyramid and the sidelength of its square base are equal. The perimeter of the base is 3 feet. Give its volume in cubic inches.

**Possible Answers:**

**Correct answer:**

The perimeter of the square base, feet, is equivalent to inches; divide by to get the sidelength of the base - and the height: inches.

The area of the base is therefore square inches.

In the formula for the volume of a pyramid, substitute :

cubic inches.
