The total outside surface is m2 the total volume is m3 Fin

The total outside surface is __ m2

the total volume is __ m3

Find the total outside surface area and volume of the solid object Assume that the base is regular. 9.1 m s 9.21 m

Solution

a) The surface area of pyramid = base area + 1/2* perimeter*slant length

base area = sqrt(3)/4*(4.9)² = 10.4 m²

1/2* perimeter*slant length = 1/2*3*4.9*9.21 = 67.69 m²

total surface area = 78.09 m²

b) toatl vome of pyramid = 1/3*base area *height = 1/3*10.4*9.1 = 31.54 m³
