A rectangular prism has a length of 6 cm, a width of 3 cm, and a height of 4 1/2cm. The prism is filled with cubes that have edge lengths of 1/2 cm. How many cubes are needed to fill the rectangular prism?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

thats not a system of equations, that is a solution

i think the length is 12 and the width is 17
