Question

Bethany is building storage boxes. Each box will have a length of 6 feet, a width of 312 feet, and a height of 512 feet. A quart of paint covers 100 square feet.

How many quarts of paint does Bethany need to buy in order to paint 5 boxes?


4 quarts

6 quarts

7 quarts

8 quarts

Answer 1

Answer:

8 quarts

Step-by-step explanation:

first, we need to find the surface area by doing 2×(6×3.5 + 6×5.5 + 3.5×5.5) = 146.5 feet(2  now we see that we have 5 total boxes so we multiply 146.5x5=732.5 1q=100 square feet so 700=7q but we still have that 32.5 left for we need 8q because it's better to have more than coming up short

Hope this helps:)

Answer 2

The number of quarts of paint Bethany needs to buy in order to paint 5 boxes is 7. The correct option is C.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Bethany is building storage boxes. Each box will have a length of 6 feet, a width of 3.12 feet, and a height of 5.12 feet. A quart of paint covers 100 square feet.

The surface area of the box will be

$\rm Surface \ area = 2(lb + bh + hl)\\\\Surface \ area = 2(6*3.12 + 3.12*5.12 + 5.12 *6)\\\\Surface \ area = 2(18.72 +15.9744 + 30.72)\\\\Surface \ area = 2*65.4144\\\\Surface \ area = 130.8288$

There are 5 boxes, then the surface area of 5 boxes will be

Surface area = 130.8288 × 5 = 654.144

A quart of paint covers 100 square feet.

Then the number of quarts required will be

$\rm Number \ o f \ quart = \dfrac{654.144}{100}\\\\Number \ o f \ quart = 6.54144 \approx 7$
