A. 285 lbs
B. 855 lbs
C. 2,565 lbs
D. 9,500 lbs

Answer 1

= 95/3 = 285

= So, the answer is 285

Answer 2

a cubic yard of gravel weighs 2,565 lbs. Option C is the correct answer.

Given:

weight of a cubic ft. of loose gravel = 95 lbs

To find:

weight of a cubic yd. of loose gravel.

Solution:

1 yd.= 3 ft.

the volume of a cubic yard= 1yd * 1yd * 1 yd= 1 cubic yd.

the volume of a cubic yard in terms of ft.= 3 ft. * 3 ft. * 3 ft.= 27 cubic ft.

weight of a cubic ft. of loose gravel = 95 lbs

weight of a cubic yd. of loose gravel = 27 times the weight of a cubic ft. of gravel

= 27 * 95 lbs= 2565 lbs.

Hence, a cubic yard of gravel weighs 2,565 lbs.
