Question

Erin built a rectangular-prism-shaped trough for her horses to eat from. The Trough is 3m long,1m wide,and 1m high ,hay for the trough costs 14$ per cubic meter . How much will it cost to completely fill the trough with hay?

Answer 1

3 x 14 = 42

$42

42 is the answer

Answer 2

you find volume by multiplying width by length by height so

3 x 1 x 1 = 3

so the volume is 3 cubic meters and every cubic meter of hay costs $14 so

3 x 14 = 42

$42
