Gavin must paint a cube shaped box the edge length is 2 1/2 feet.

What is the surface area of the box.

Ps, sa=6s2

Surface area of the box = 37.5 square feet

Solution:

Edge length of the cube (a) = ft

Convert mixed fraction into improper fraction.

Surface area of the cube = 6a²

                                          = 37.5 square feet

Surface area of the box = 37.5 square feet

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
