Barb is going to cover a rectangle area 8 feet by 10 feet with rectangle 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?
1 answer:
Step-by-step explanation:
First, transform 8 feet and 10 feet into inches so we can work with the same measurements
8 * 12 = 96 in
10 * 12 = 120 in
Next find the patio rectangle area.
96 * 120 = 11520 in^2
Now find the paving block area
4 * 8 = 32 in^2
Now, find out how many paving blocks will go into the patio rectangle area.
11520 / 32 = 360
The minimum number is 360 paving blocks
