Problema Solution
The bead is a rectangular prism of length 17 mm, width 9 mm, and height 5 mm. A 3 mm wide hole is drilled through the smallest face. Find the volume of the bead.
Answer provided by our tutors
Volume before being drilled: V = l*w*h
Volume after being drilled: (l*w*h) - l*pi*r^2
V before: 17*9*5 = 765 mm cubed
V of drilled area: (17)*pi*(1.5)^2 = 120.17 mm cubed
V after: 765 - 120.17 = 644.83 cubic mm
