Answer:
Step-by-step explanation:
Let the length be L
Formula
SA = 2Lw + 2Lh + 2wh
Givens
h = 15 cm
w = 6 cm
L = ?
SA = 684 cm^2
Solution
Substitue what you know into the given formula
2*6*L + 2*15*L + 2 * 6 * 15 = 684 Combine
12*L + 30*L + 180 = 684 Combine again
42L + 180 = 684 Subtract 180 from both sides.
42L +180 -180 = 684 - 180
42L = 504 Divide by 42
Answer: L = 12
Answer: A) 18
You divide the 12 cups of juice into 2/3 which will give you 18.
Equation: 12/1 divided by 2/3 = 18
Step by Step:
12/1 divided by 2/3
12*3 / 1*2 = 36/2
36 divided by 2 = 18
