Step-by-step explanation:
If the ratio is 3:5, then for every 3 boys there are 5 girls, so you multiply 3 and 5 by 24 and you get your answer.
Answer: ?=7
Explanation: Use pythagorean theorem
Total SA = top + bottom + 2 (short side) + 2 (long side)
top = bottom = 5×3 = 15
short side = 7×3 = 21
long side = 7×5 = 35
SA = 2 (15) + 2 (21) + 2 (35) = 30+42+70 = 142
So 142 - 121 = 21, so the missing face is a short side of 7×3
