Answer 1

Answer:

The rectangular prism is 16 inches long.

Step-by-step explanation:

Given:

Bradley has 64 1-inch cubic blocks.He uses all the blocks to build a rectangular prism that is 2 inches high and 2 inches wide.

Now, to find the length of rectangular prism.

Volume of rectangular prism = 64 cubic inches.

Height of rectangular prism = 2 inches.

Width of rectangular prism = 2 inches.

Now, to get the length we put formula:

$Volume=length\times width\times height$

$64=length\times 2\times 2$

$64=length\times 4$

Dividing both sides by 4 we get:

$16=length\\\\length = 16\ inches.$

Therefore, the rectangular prism is 16 inches long.
