Barb is going to cover a rectangular area 8 feet by 10 feet with rectangular paving blocks that are 4 inches by 8 inches by 2 inches to make a flat patio. What is the minimum number of paving blocks she will need if all the paving blocks will face the same direction?

Question

(Note: Barb will not cut any of the paving block.)

A. 80
B. 360
C. 601
D. 960
E. 1,213

Answer 1

8 ft = 96 inches
10 ft = 120 inches

96 / 4 = 24
120 / 8 = 15

24 * 15 = 360 blocks

Answer 2

Thank you so much Ms. Sue. This question was confusing. Two times I kept getting 106.

Answer 3

You're welcome. The key, as you see, was to convert feet to inches.
