There is a rectangle, its length, width and height are three continuous natural numbers, and its volume is 210 cubic meters?
Length, width and height are three continuous natural numbers, and the volume is 210 cubic meters
---
It is concluded that the length, width and height are 5m, 6m and 7m
So the surface area of the cuboid is 2 * (5 * 6 + 6 * 7 + 5 * 7) = 214 (square meters)
The surface area of a cube is 36cm. How many cm does it cover
36/6=6cm^2
