Acandy store called "sugar" built a giant hollow sugar cube out of wood to hang above the entrance to their store. it took 54 feet^2 of material to build the cube. what is the volume inside the giant sugar cube?

the volume is  27 ft^3

Step-by-step explanation:

We have that the surface of the cube is 54 ft^2

first, remember that a cube has 6 equal faces, this means that each face of the cube has a surface of:

f = (54/6) ft^2 = 9ft^2

each one of those faces has the same length in each side, and the surface of a square is equal to the length of one of the sides squared:

f = L^2 = 9ft^2

L = √( 9ft^2) = 3ft

now, the volume of a cube is equal to the cube of the length of the side:

v = L^3 = (3 ft)^3 = 27 ft^3

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
