Wooden 3
A wooden board 2.5 m long has a cross-section in the shape of a right-angled trapezoid whose parallel sides are 1.2 dm and 8 cm long. The height of the trapezoid is 3 cm. Calculate:
a) the surface area of the board, to determine the amount of stain needed,
b) the weight of the board if the density of the wood is 600 kg/m³,
c) how many such boards can be loaded onto a 3-tonne truck.
Your answer:
a) the surface area of the board, to determine the amount of stain needed,
b) the weight of the board if the density of the wood is 600 kg/m³,
