the perpendicularheight, will give the solid contents. Note This rule holds equally true to a pyramid of anyform. For the solidities of pyramids are equal when theyhave equal heights and bases, whatever be the figure of theirbases.

Then, V40OX 196 = 280. And, 596 + 280x33^=29200.29200-1728 = 16-9 cubic feet. Ans.To find the weight, 169x 169 = 2856 lbs. Ans. Note. By this rule, marble cutters can easily determine…
