What is the surface area of a cube with a side of 13sqrt(5)
note: answer must not be a fraction or a decimal

A cube has six square sides.  Supposing that the length of each edge of the sides is s, then the area of each side is s^2.  Multiplying that by 6 gives the total surface area of the cube:  A = 6s^2.

We are told that the side length is 13sqrt(5).  Thus, substitute this value for s in A = 6s^2.  Since s=13sqrt(5), A = 6 (13sqrt(5))^2, or 6 (169) (5), or 30(169) square units.  Simplify this by multiplying 169 by 30.

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?
