You were interested in buying a gift that is shaped like a cube for your friend you have two different sizes to choose from one has a side length of 1.9ft and the other is 1.6ft in length you only have 36 square yd of wrapping paper. is there enough wrapping paper for box 1, box 2 and both boxes

Step-by-step explanation:

Since a cube has 6 faces with equal lengths

Total surface area of Box 1= (1.9×1.9)6=21.66ft²

Total surface area of Box 2=(1.6×1.6)6=15.36ft²

Wrapping paper available=36yd²

Since 1yd²=9ft², convert 36yd² to ft²

36×9=324ft²

324/21.66=14.96, meaning the wrapping paper is enough for 14 of the Box 1 type

324/15.36=21, meaning the wrapping paper is enough for 21 of the Box 2 type

Total surface area of both boxes=21.66+15.36=37.02ft²

324/37.02=8.75,meaning the wrapping paper is enough for at least 8 of both Boxes

Is there enough wrapping paper for both boxes

Step-by-step explanation:

we know that

The surface area of a cube is equal to

where

b is the side length of the cube

step 1

Find the surface area of box 1

we have

substitute in the formula

step 2

Find the surface area of box 2

we have

substitute in the formula

step 3

we have  36 square yd of wrapping paper

Convert square yards yo square feet

Remember that

1 yd=3 ft

Adds surface area box 1 plus surface area box 2

therefore

Is there enough wrapping paper for both boxes

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

answer is c

step-by-step explanation:

81/12=324/x

x=48
