To find the base area,
70.56N / (4900N/m^2) = 0.0144 m^2 = 144cm^2
v = 1/3 * 144 * 15 = 720 cm^3
A square based pyramid, with a perpendicular height of 15cm I'd placed on a table.
The weight of the pyramid is 70.56N. The pyramid exerts a pressure of 4900N/m^2 on the table.
Work out the volume of the square based pyramid.
Thank you so much.
