Calculate the values of A, B, C and D.
Amanda sold 6 of the 12 stickers which she had bought at 75 cents each, and
the remaining stickers at 40 cents each.
Show, using calculations, whether Amanda made a profit or loss on buying and
selling stickers.
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.

Show, by calculation, that the internal capacity (volume) of the trough is 8 091 000 cm³.
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)
