Jason had a 3cmx3cmx3cm wooden cube. He removes a 2cmx2cmx2cm wooden cube from one corner of the 3cmx3cmx3cm cube. What is the surface area in square cm, of the remaining solid that has a volume of 19 cubic cm?

13.46

step-by-step explanation:

16.80 x .20 = 13.46

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
