Explanation Given: Weight of casting W = 5 .82 lb Length of sides s = 5 .70 in . Height h = 4 .65 in . Calculation: The volume of a regular pyramid is V = 1 3 A B h Where, h = height, and A B = Base area. Since, the shape of the base of the pyramid is triangular. The base area of triangle is A b = 1 2 × b × h A b = 1 2 × 5.70 × 4.65 A b = 13.25 i n . 2 Thus, the volume of the pyramid is V = 1 3 ×13 .25×4 To determine (b) The weight of one cubic inch of cast iron.
