wren wants to build a box to organize her scrapbook supplies.She has a stencil set that is 12 inches wide that needs to lay flat in tne bottom of the box.The supply box must also be no taller than 2 feet.Name one way she could build a supply box with volume of 72 cubic inches

Answers

Given:
Width 12 inches
Height 2 feet
Volume 72 cubic inches.

Volume = Length * Width * Height

We need to find the length of the box. But, we need to convert the height from feet to inches to find the length in inches.

1 foot = 12 inches

2 ft * 12 inches/1ft = 2 * 12 inches = 24 inches
Height should be 24 inches or less.

H < 24 inches

V = L * W * H
72 inches³ = L * 12 in * H
72 in³ ÷ 12 in = L * H
6 = L * H

Given the measure of 6 inches for Length and Height, these can be the combination:

1 * 6 = 6
2 * 3 = 6

V = L * W * H
72 in³ = 1 in * 12 In * 6 in
72 in³ = 72 in³

or

72 in³ = 2 in * 12 in * 3 in
72 in³ = 72 in³

One way she could build a supply box with volume of 72 cubic inches is 12 in x 3 in x 2 in

Further explanation

A square is a regular quadrilateral, it has four equal sides and four equal angles (90-degree angles, or 100-gradian angles or right angles).
