Well because they gave us a few numbers in the question, it is certain that the other side could be the same number as the left side so x=(2)+3 y=(1)+1
First find the volume of brick = 18 * 9 * 6 = 972 cm^3
volume of wall
Take note of units in meters. 1m = 100 cm
so we have 4.5 * 100 * 18 * 3.6 * 100 = 2,916,000 cm^3
So we divide the volume of wall by volume of brick to know how many bricks required
2,916,000/972 = 3,000 bricks
Answer:
V = 159 3/8 cm^3
Step-by-step explanation:
V = l*w*h
V = 8 1/2 * 5 * 3 3/4
Change to an improper fraction
V = 17/2 * 5 * 15/4
V =1275/8
Changing back to a mixed number
8 goes into 1275 159 times with 3 left over
V = 159 3/8 cm^3
