Question 1043795: the side of one cube are twice as long as the side of a second cube. what is the side lenght of each cube if the total volume of the cube is 72cm3
You can put this solution on YOUR website! I'm assuming the combined volume is 72 cm^3.
cube a: side is x, volume is x^3
cube b: side is 2x, volume is 8x^3
Their sum is 9x^3=72 cm^3
Therefore x^3=8 cm^3; take the cube root of both sides.
x-2 cm, so cube a has a volume of 8 cm^3
2x=4 cm, so cube b has a volume of 64 cm^3
They sum to 72 cm^3.
a has a side of 2 cm
b has a side of 4 cm
