A rectangular sheet of metal which measures 120cm by 0.8m is 1.5mm thick and is made of material whose density is 2.2 g/cm3. From each of the four corners of the rectangle, a square of side 10cm is cut off and the remaining part folded to form an open cuboid.
- the capacity of the cuboid in cm3 to the nearest whole number
- the mass of the empty cuboid in kg to the nearest whole number
- the cuboid is filled with a liquid whose density is 0.75g/cm3. Calculate the mass in kg of the cuboid when full of the liquid
- calculate the mass of metal lost in kg
