Question

Predict how many centimeter cubes will fit in the box, and briefly explain your

prediction. Use cubes to find the actual volume. (The figure is not drawn to
scale.)

Answer 1

Prediction: 12 cubes, since there are two rows of three stacked on top of two rows of three (6 + 6)

Actual: 12 cubes

Explanation:

Looking at the figure, you can see 6 cubes facing you, so two rows of three cubes or three columns of two cubes - either way 3 x 2 = 6. Since you can also see the side of the box, you see that there are 6 more cubes behind the first ones, so an additional two rows of three cubes or three columns of two cubes - either way 3 x 2 = 6. So, the total number of cubes is 6 + 6 = 12.

Volume can also be found by multiplying the length x width x height:

3 cubes x 2 cubes x 2 cubes = 12 centimeter cubes
