Question

9 cu yd 113 cu in - 4 cu ft 129 cu in

Answer 1

Answer:

=8 yd³ 22 ft³ 1712 in³

Step-by-step explanation:

To perform the indicated operation we need to convert the given measurements of volume to common units.

1 yd = 3 ft

1 yd³=27ft³

1 ft³=1728 in³

Thus 9 yd³=(27×9)ft³

=243 ft³

113 in³ into ft= 113/1728

9 yd³ 113 in³= 243  113/1728 ft³

4 ft³ 129 in³= 4 129/1728 ft³ = 4 43/576 ft³

Performing the operation given in the equation:

243  113/1728 ft³ - 4 43/576 ft³ = 238  1712/1728 ft³

238 ft³= 8 yd³ 22 ft³ + (1712/1728) × 1728

=8 yd³ 22 ft³ 1712 in³
