Question

How many cubic blocks with a side length of 1/8 inch are needed to fill a rectangular prism with a length, width, and height of 3/4 inch 1/2 inch, and 1/2 inch, respectively?

Answer 1

volume of cube is V=S^3

so 1/8 = 0.125 = 0.125^3 = 0.00195 in^3

volume of rectangle

V= l x w x h = 0.75*0.5*0.5 = 0.1875 in^3

0.1875/0.00195 = 96.15 round to 96 blocks
