A shipping container is shaped like a rectangular prism. The height is 16 feet and the length is 11 feet. If the volume of the toolbox is 1,408 feet cubed, what is the width?
width = 8ft
h x w x l = V
16 x w x 11 = 1,408
176 x w = 1,408
1,408/176=8

Which expression would have a greater product?
How do you know?
47 x 16 OR 47 x 24
47 x 24 because the first expression is only 16 groups of 47 and the second expression is 24 groups of 47, 8 more groups. Therefore, the product will be larger because there are more groups of the same number.
The area of a cafeteria is 1,724 square feet. It has a height of 17 feet.
Explain why the volume of the box is less than 40,000 feet cubed.
The volume is less than 40,000 feet cubed because 1,724 rounds to 2,000 and 17 rounds to 20.
2,000 x 20 = 40,000, however, the factors you would use to find the exact volume, 1,724 and 17, are smaller than their estimates, therefore the exact answer will also be smaller than the estimate.
