Answer:
C) 7×10^8/(5×10^3)
Step-by-step explanation:
In cubic inches, the volume of a bucket of sand is ...
(π/4)(20 in)²(15 in) = 1500π in³ ≈ 5×10^3 in³
__
The volume of the warehouse is
(250 ft)(80 ft)(20 ft) = 400,000 ft³ = 4×10^5 ft³
The conversion to cubic inches is ...
(4×10^5 ft³)(1728 in³/ft³) = 4×1.727×10^8 in³ ≈ 7×10^8 in³
Dividing the warehouse volume by the bucket volume gives the approximate number of buckets that will fit in the warehouse:
(7×10^8)/(5×10^3) . . . . . matches choice C
