Question

What is The lateral area of a right rectangular prism that has rectangular faces measuring 3” x 5” and a height of 6 feet

Answer 1

1152 square inches

Explanation:

The lateral area of a a right rectangular prism is given by the equation;

Lateral area=(2l+2w)h where l is the length , 5 inches, w is the width of 3 inches and h is height of (6×12=72 inches).

Lateral area= (2×5 + 2×3) × 72

=(16)× 72

=1152 square inches

Answer 2

Answer: 1152 in²

Explanation:

You can calculate the lateral area of a rectangular prism with the formula shown below:

`L=Ph`

Where P is the perimeter of the base and h is the height.

The formula for calculate the perimeter of the base is:

`P=2l+2w`

Then, the lateral area is:

`L=(2l+2w)h=(2*3in+2*5in)(72in)=1152in^(2)`

(1 in=12 ft, therefore 6ft=72 in)
