Surface Area and Volume Math 7

Daniel builds a concrete patio that is 6 in thick, 12 ft. wide, and 20 ft. long. The premix concrete cost $2 per cubic foot. How much did the concrete cost? (watch the inches! change it to feet first! then VOLUME then cost)

• $120

• $240

• $480

A cardboard box is in the shape of a rectangular prism. It has a length of 2.3 m, a width of 1.4 m, and a height of 0.5 m. What is the volume of the box?

• 1.61 m cubed

• 4.20 m cubed

• 6.44 m cubed

Find the difference in the volume of the two boxes. The dimensions of box one are 5 cm by 5 cm by 5 cm. The dimensions of box two are 5cm by 6 cm by 4 cm. (the DIFFERENCE between the two boxes!)

• 0 cm^3

• 5 cm^3

• 15 cm^3
