DanielleElmas [232]

<u>Question Correction</u>

Simon fills a container with 38 1-in, cubes. The container is a box of dimension 4 in. by 3 in. by 4 in.,How many more 1 in cubes does the container need to  be completely filled?

Answer:

10 1-in cubes

Step-by-step explanation:

First, we determine the Volume of the box.

Volume of a Rectangular Prism =Length X Height X Width

Volume of the box = 4 X 3 X 4= 48 cubic inches

To fill the box container, we would need 48 1 in cubes.

Since Simon already filled the container with 38 1-in, cubes.

Number of 1-in. cubes required to fill the box

=48 -38

=10.

Simon would need 10 1-in cubes to fill the box.
