Answer:
466,56 inches
Step-by-step explanation:
1 yard = 36 inches
1 cubic yard = 36*36*36 = 46656 cubic inches
46656 = 20*5*l => l = 46656/100 = 466, 56 inches
Answer:
117 ft
Step-by-step explanation:
1 yd³ = 36³ in³ = 46656 in³
Volume = ⅓ (5 × length) × 20
46656 = ⅓ (5 × length) × 20
length = 1399.68 in
1399.68/12 ft
= 116.64 ft
