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

Answer: 1152 in²

Step-by-step 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)

Answer 2

Answer:

1152 square inches

Step-by-step 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
