Question

find the weight density of a block 7.00 in. * 6.50 in. * 8.00 in. that weighs 50 lb.

science physics

Answer 1

Answer #1

Weight density is defined as:

D = Weight/Volume = 50 lb / ( 7 x 6.5 x 8 ) in³ = 0.137 lb/in³

we know 1 ft = 12 inch, so 1 inch = 1/12 ft

Hence D = 0.137 x 12³ lb/ft³ = 237.36 lb/ft³
