PLEASE HELP ME DONT SKIP!

Answer 1

$128 is the answer.
The carton has a volume of 512 square inches because since it is a cube 8 inches tall, that is also the length and width. Each plastic cube is 1 square inch, so 512 cubes will fit. All the cubes in total will cost $128 .

Answer 2

If the carton is shaped like a cube, the length will be equal across all sides.
So every side length (length, width, height) is 8 inches.

Find the volume of the carton (cube) to see how many colored plastic cubes fit into the carton. 

Volume of a cube: length x width x height, or side length cubed.

Plug 8 inches into the formula: 8 x 8 x 8 = 512 inches³

The carton can fit 512 cubes. If each cube is 25 cents each, multiply 512 by 0.25 to get how much it would cost to buy all the cubes.

512 x 0.25 = 128

It would cost $128 to buy all the cubes in the carton.
