questions 1) 1st work out the surface area. Work out the area of the square and then add that to the 3 quarters of the circle as a quarter is inside the square. Then multiply this number by the height.
an extremely quick calculation got 47265 but that could be wrong

Generally speaking, the volume of a prism is the cross sectional area times the length
Guy above gave correct answer, area of square plus 3/4 area of circle (pi * radius squared) all times by the height
Second question, add up the area of the six rectangles and add the four triangles |(1/2 times base times height) then times this cross sectional area by the length (in this case 12m)
