Question:

A block of steel has a density of 0.29 pounds per cubic inch. If the block has dimensions of 1 inch by 1 inch by 3 inches, what is its weight?

A 0.87 pounds
explanation

The volume of the block can be calculated by multiplying its length by its width by its height, or 1 times 1 times 3, which equals 3 cubic inches. The weight is the density multiplied by its volume, which is 3 cubic inches multiplied by 0.29 pounds per cubic inch, which equals 0.87 pounds.

App is pretty good overall some of the modules like visual assembly are horrendous because you can barely see. Some of the explanations for right answers aren’t thorough.
