Given:
Length of the playground: 125 ft
Width of the playground: 60 ft
Depth of the mulch: 6 inches
Convert ft and inches to yards
1 yard = 3 feet
Length: 125ft/3ft = 41.67 yd
Width: 60ft/3ft = 20 yd
1 ft = 12 inches
Depth: 6 inches * 1ft/12inches = 6ft/12 = 1/2 ft
Depth: 0.5 ft * 1yd/3ft = 0.5yd/3 = 0.17 yd
Volume = Length * Width * Depth
V = 41.67yd * 20yd * 0.17yd
V = 141.68 yd³
V = 125ft * 60ft * 0.5ft
V = 3,750 ft³
1 cubic yard = 27 cubic feet
3,750ft³ * 1yd³/27ft³ = 3,750 yd³ / 27 = 138.89 or 139 yd³ LETTER B.
