Answer:
The surface area would be 28 square feet.
Step-by-step explanation:
To solve this, input the values for each of the variables every time you see it. l = length, w = width and h = height.
SA = 2lw + 2hw + 2hl
SA = 2(2)(1) + 2(4)(1) + 2(4)(2)
SA = 4 + 8 + 16
SA = 28
$7.5 * 10^9 = $7.5 * 1,000,000,000 = $7,500,000,000
It is seven billion, five-hundred million dollars.
If there is 6 times as many blue cars as white cars, share it in the ratio 6:1.
6 + 1 = 7
35 ÷ 7 = 5
6 x 5 = 30
1 x 5 = 5
Answer: 30 blue cars and 5 white cars
