Question

How many 4 x 8 sheets of sheetrock will fit in a 24 x 26 roof

Answer 1

the answer is 19
24x26=624
4x8=32
624/32=19.5 so you round down to 19

Answer 2

Roof area= 24 x 26 = 624

Sheets area= 4 x 8 = 32

Then now divide

= Roof area/Sheets area= 624/32 = 156/8= 39/2

=39/2= 19.5. (take integer part only)

Then answer is

19 sheets of sheetrock will fit
