Problema Solution
Plywood is sold in rectangle sheets 4 feet wide and 8 feet long. How many 4x8 sheets of plywood are needed to completely cover a rectangle shaped floor measuring 16 feet by 12 feet.
Answer provided by our tutors
16 and 12 are each evenly divisible by 4, 16 is evenly divisible by 8, so we use 2 8-foot sheets along the 16-foot dimension and know that the entire area will be evenly covered by full sheets of plywood
total area to cover:
16*12 = 192
number of sheets of plywood necessary:
192/(4*8) = 6
a total of six sheets of plywood will be necessary
