Question

An American engineer who had been transferred to Europe was asked to build bridge pilings exactly as he had in the United States. Each piling required 20.0 cubic yards of concrete in the United States. How many cubic meters of concrete are required for each piling? Given: + 1 yd = 0.914 m.

Answer 1

I think it's 15.3 cubic meters but I'm not sure. I joined this thing to double check my answer but I can't find the answer on here T_T

Answer 2

Answer:

15.27 $m^{3}$

Explanation:

1 yd = 0.914 m

How we have an equation, if we do anything on the left, we may do the same thing on the right and the equality must continue. So, puting all the elements in cubic:

$(1 yd) ^{3} = (0.914 m)^{3}$

$1 yd ^{3} = 0.763 m^{3}$

Then

$1 yd ^{3} -------------------- 0.763 m^{3}$

$20 yd^{3} --------------------- x$

x = 20x0.763

x = 15.27 $m^{3}$
