Question

If a cube has a surface area of 294cm what are the dimensions and what is its volume? ?

Answer 1

6x^2=294

x^2=49

x=7

7^3=343

make it a good day

Answer 2

Well, since we know a cube has six equal sides, we can find out the area of one side by saying

294/6 = a(1)

a(1) = 49

And we know that each side is a square, so all the edges are equal

And we find the area of a square by multiplying the edge by itself

To go backwards, we find the square ROOT of the area

49(sqrt) = 7

So the length of an edge on the cube (it's height, width, OR length) is 7cm

And to find the volume we simply cube that length

7x7x7 = 343cm^3
