Given a tank measures 50
feet long, 25 feet wide, and 15 ft deep, calculate:
- Surface area in ft2
- Cross-sectional area in
square feet
- Volume in cf
- Capacity in gallons
The correct answers are:
Surface area in ft2
= Length, ft x Width, ft = 50 ft x 25 ft = 1250 ft2
-
Cross-sectional area in square feet
Cross-sectional area in ft2 =
Width, ft x Depth, ft = 25 ft x 15 ft = 375 square feet
Volume in cf = Length, ft x Width, ft x
Depth, ft = 50 ft x 25 ft x 15 ft = 18,750 cf
Capacity in gallons = Volume in cf x 7.5
gal/cf = 18,750 cf x 7.5 gal/cf = 140,625 gal
