Answer:
I think 15
Step-by-step explanation:
Because there are 3 in every 20 and 20 goes into 100 5 times and 5×3=15
Step-by-step explanation:
120ft³ = 3ft × 4ft × 10ft
120ft³ = 1ft × 1ft × 120ft
120ft³ = 2ft × 2ft × 30ft
120ft³ = 5ft × 3ft × 8ft
...
Taking fractions or mixed numbers as dimensions, you can give infinitely many such shapes with a volume of 120ft³.
3*7= 21 65*70= 4,550 5*21= 105*4,550=477,750
