Mice21 [21]

Answer:

The correct answer is 75 cubic feet.

Step-by-step explanation:

Volume of each block of cube is 1 cubic foot. Since the block is of the shape of a cube, the side length is 1 foot.

Number of blocks needed to fill the bottom of the the chest is 25.

Height of the chest is 3 feet.

Therefore there are three layers to be filled by blocks. Each layer needs 25 blocks each. Thus number of blocks needed to fill the whole chest is 25 × 3 = 75.

Volume of 75 blocks = Volume of the chest = 75 × 1 = 75 cubic feet.

Therefor the volume of the chest is given by 75 cubic feet.

Using the picture, we know (2x+6)+(5x-3)=24. Simplify to find x.

7x+3=24
7x=21
x=3

We know AB=2x+6, and x=3. Plug 3 in for x.
AB=2(3)+6.
AB=6+6
AB=12
