you are going to make a box out of cardboard.
the box needs to measure 10cm by5cm by 5cm;
10% of the finale product will be wasted in the cutting process.
how much cardboard do you need
:
Find the surface area of the closed box
S.A. = 2(10*5) + 2(10*5) + 2(5*5)
S.A. = 100 + 100 + 50
S.A. = 250 sq/cm for the box
:
Let a = amt of cardboard required
then
.1a = wasted amt
:
a = .1a + 250
a - .1a = 250
.9a = 250
a = 250%2F.9
a = 277.78 sq/cm required
