The volume of a rectangular parallelepiped is calculated by the formula V = abc, where a, b and c are the lengths of its three edges going out from one vertex. Using this formula, find a if V = 70, b = 5 and c = 3.5.
To solve this problem, it is necessary to express one of its edges a from the formula for the volume of a rectangular parallelepiped. Let’s do it:
a = V / bc,
that is, you need to divide the volume by the lengths of the remaining ribs.
Substitute the given values into the resulting formula and find a:
a = 70 / (5 * 3.5) = 4.
Answer: the edge a of a rectangular parallelepiped is 4.
