Aquarium II

Calculate how much glass we need to build an aquarium with a rectangular shape with base 70 cm × 70 cm and a height of 70 cm, if the waste is 2%. Aquarium haven't top glass.

Result

x =  2.5 m2

Solution:

x=1.02(0.70.7+20.70.7+20.70.7)=2.5 m2x = 1.02 \cdot (0.7 \cdot 0.7 + 2\cdot0.7\cdot0.7 + 2\cdot0.7\cdot0.7) = 2.5 \ m^2
