Answer:
The side length of the cube is 6 cm
Step-by-step explanation:
The volume of a cube is given by
V = s^3
We know the volume is 216
216 = s^3
Take the cube root of each side
216 ^ (1/3) = s^ (1/3)
6 = s
The side length of the cube is 6 cm
D / 16 = t^2
when d = 64
64 /16 = t^2
t^2 = 4
t = 2
answer is 2 seconds
So if he drives 50 miles in 1 hour, then he must drive 100 miles in 2 hours. 0.25 is another way of writing 1/4, and to find 1/4 you divide by 4, so 50 ÷ 4 = 12.5 miles. Then you can add this to 100 and get your answer as 112.5 miles.
If you have a calculator, or if you're allowed a calculator, then a simpler way is to just do 2.25 × 50 = 112.5
Hope this helps!

= 1/3×( 22/7 × 7²×9)
= 1/3× (22/7 × 49 × 9)
= 1/3×(22×7×9)
=1/3× (154×9)
=1/3× 1386
= <em>462 cubic </em><em>yards</em>
