6. MEASUREMENT Farmer Brown makes troughs to feed his farm animals, using wood that is 5 cm thick. As shown in the diagram below, the troughs are rectangular-based, open at the top and have external dimensions of 300 cm by 190 cm by 160 cm. 5cm (a) -300 cm 190 cm 160 cm Show, by calculation, that the internal capacity (volume) of the trough is 8091 000 cm. Calculate the volume of wood needed to make a trough. Farmer Brown must paint the INTERNAL surface of the trough. Given that I gallon of paint covers approximately 280 000 cm³ of surface, determine the TOTAL amount of paint, in litres, that is needed to paint the internal surface of the trough. (1 gallon = 3.79 litres)
