Answer:
-5/12
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Step-by-step explanation:
since all sides of a cube have the same length (same principle as e.g. for a square), this means also the length and width are 10 in long.
the volume is therefore
10 × 10 × 10 = 1000 in³
They make 21 machine parts each hour because 756/36=21
