Question

seven pints of water are needed to water each square foot of lawn. At least how many gallons of water are needed to water a lawn 12 feet by 16 feet.

Answer 1

Find total area: 12 x 16 = 192 square feet.

7 pints are needed for each square foot , multiply total square feet by 7 pints to find total pints needed:

192 x 7 = 1,344 total pints.

1 gallon = 8 pints.

Divide total pints needed by 8 to get gallons:

1,344 / 8 = 168

168 gallons are needed
