Step-by-step explanation:
<u>Area Of A Cube
</u>
Suppose a cube with side length s, the area of one side is

Since the cube has 6 sides, the total area is

But if we have the area, we can solve the above formula for s to get


We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths




The difference between them is

The side of the cube with area 1,200 square inches is
longer then the side of the cube with area 768 square inches

Answer:
Number of gallons of blue paint = 40 gallons
Number of gallons of red paint = 25 gallons
Step-by-step explanation:
We are given the ratio:
Blue paint : Red paint =
8 : 5
Sum of proportion = 8 + 5 = 13
If the customer need 65 gallons of paint,
a) Number of gallons of blue paint needed =
8/13 × 65 gallons = 40 gallons
b) Number of gallons of red paint needed =
5/13 × 65 gallons = 25 gallons
Therefore:
Number of gallons of blue paint = 40 gallons
Number of gallons of red paint = 25 gallons
