3/162=3/60+3/120 3/162 is equal to 2/152
Answer:
9/0
Step-by-step explanation:
Answer:
Step-by-step explanation:
The volume of a cube.
The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.
That's why the formula is written as V = s^3. It means that V = s * s * s which is three sides multiplied together. They also need to be at right angles to each other.
Answer:
The scale factor will be 0.25 and the length of the side will be 8.75 cm. Hope it helps :)
