# Concrete tank

How many m3 of concrete is in the tank shape of a cuboid with dimensions of 2000 cm and 5.6 meters and 70 dm, if the concrete takes up 3/7 of the tank?

Result

V =  336 m3

#### Solution:

$a = 2000/100 = 20 \ \\ b = 5.6 \ \\ c = 70/10 = 7 \ \\ V = a \cdot \ b \cdot \ c \cdot \ 3/7 = 20 \cdot \ 5.6 \cdot \ 7 \cdot \ 3/7 = 336 = 336 \ m^3$
