Marta has 1 cubic yard of sand to build a wall in the shape of a rectangular prism that is 20 inches tall and 5 inches wide. To the nearest foot, what will be the length of this wall?

Answers

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
