A cube has a volume of 216 cubic inches, and another cube has a volume of 729 cubic inches. What is the ratio of the surface area of the larger cube to the surface area of the smaller cube?

Ratio is

You can simplify it of course to 3/2

Step-by-step explanation:

Volume of a cube is V = length^3 or l^3

Volume for larger cube = 729 cubic inches

Volume for smaller cube = 216 cubic inches

Surface area is S = 6*l^2

So we just need to find the length of each side of the cube.

We take the cube root for each cube volume since there are three sides.

Larger cube = 729^(1/3) = 9

smaller cube = 216^(1/3) = 6

Ratio is

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
