Answer:

430 cubic centimeters

Explanation:

Lets start by separating both figures. Start with the one in the back, which is the bigger one.

Given:

Length = 10 cm

Width = 3 cm

Height = 9 cm

This is a rectangle and the volume of a rectangle is L x W x H. Therefore,

Volume = 10 x 3 x 9 = 270 cubic centimeters

Now we move on to the second figure.

Given:

Length = 10 cm (Given from the other rectangle)

Width = 8 cm (We do 11 - 3 since we separated the rectangles)

Height = 2 cm

Using the same formula we get the following.

Volume = 10 x 8 x 2 = 160 cubic centimeters

____

Finally, we add both volumes back since we separated the figures in the beginning.

Volume = 270 + 160 = 430 cubic centimeters
