Question

Brian is creating a collage on a piece of cardboard that has an area of 150r2 square centimeters. The collage is covered entirely by pieces of paper that do not overlap. Each piece has an area of the square root of r cubed square centimeters. Use the given information to determine an expression for the total number of pieces of paper used.

Answer 1

See, the area of paper pieces given is : r^3

So, divide the full area by this area to get the answer..

Divide it:

\[\huge \frac{150r^2}{r^3}\]

Answer 2

thank you

Answer 3

how would you divide that with r2

Answer 4

\[\huge = \frac{150 \cancel{r} * \cancel{r}}{\cancel{r}*\cancel{r} * r}\]

Answer 5

so its 150 over r

Answer 6

Yes..
