If this is a box, the total surface area would be 1120 units2 which is found by adding the area of all of the faces. So, 10 x 20 x 2 (because there are going to be two faces with this area) + 20 x 12 x 2 + 10 x 12 x 2. This is 1120. The volume would be 2400 units3, found by length x width x height.
Convert 20' x 10' to inches: 20*12 " x 10*12 " = 240x120. Then find the area of both: 28800 for 20 by 10 and 144 for 12 by 12. Divide: 28800/144 is equal to 200.
Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2
Diameter = 20 inch => radius = 10 inches = 10/12 feet. So area = pi*(10/12)^2 = 2.1817 sq feet approx.
20 + 10 - 12 = 18
The LCM is 60.
96 cm2
1 feet is equal to 12 inches. so... area of pool= 4 x 20 x 10 = 800 feet 800 feet x 12 inches = your answer...
20/10 + 10 = 12 20/(10 + 10) = 1
2 x 10 = 20 2 + 10 = 12
2 and 10. 2*10=20 2+10=12
10 percent = 60/10 = 6 10 percent + 10 percent = 6 + 6 = 12 20% of $60 is $12
2 is the GCF of 10, 12, and 20.
