If the dimensions of a pentagonal prism are quadrupled, then the surface area of the prism is multiplied by eight.
Lubov Fominskaja [6]

Answer:

false

Step-by-step explanation:

the relationship between lengths/dimensions and areas is that areas are created by multiplying 2 dimensions.

when you quadruple (×4) the dimensions, then the areas are growing with the square of the factor (×4×4 = ×16), because the factor goes twice into the multiplication : one time for every dimension involved.

so, quadrupling the dimensions would multiply the areas by 16.

Jenna uses 18 inches of ribbion for each box she wraps how many yards of rib ion does she need to wrap 4 boxes
Sav [38]
Hello Myeisha91! 

First we need to find how many inches in total to wrap 4 boxes. We do that by multiplying 18 x 4 = 72 so Jena needs 72 inches. The question wants to know how many yards so we need to convert 72 inches into yards. We can convert inches to yards by using a conversion factor. We know that 1 inch = 0.0277778 yd. Now that we know  1 inch = 0.0277778 yd, lets convert the 72 inches to yards.

We convert 72 in to yards by multiplying 72 in by \frac{0.0277778\;yd}{1\; in}
72\;in\times\frac{0.0277778\; yd}{1\;in} = 2\; yd
So Jenna will need 2 yards to wrap 4 boxes.
