Answer:
He got 16 incorrect
Step-by-step explanation:
Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x height
Multiply 1300 mm by 800 mm to get 1040000 mm. Then convert this to meters. 1 meter=1000 mm. Therefore, 1040000 mm is the same as 1040 meters.
Answer:
1. x = 12
2. x = 5
Step-by-step explanation:
1. -222 = -2x - 12x - 54
-222 = -14x - 54
-168 = -14x
x = 12
2. 154 = 2x + 12x + 84
154 = 14x + 84
70 = 14x
x = 5

Answer:
196π cm^3 ≈ 615.8 cm^3
Step-by-step explanation:
Put the numbers in the volume formula and do the arithmetic.
V = 1/3πr^2·h
V = 1/3π(7 cm)^2(12 cm) = 196π cm^3 ≈ 615.8 cm^3
