Since the base is a regular quadrilateral, each of its 4 sides must have length s = P/4 s = (60 cm)/4 = 15 cm
The area of one lateral face is the product of side length and height. A = s×h 105 cm² = (15 cm)×h Then the height of the prism is h = (105 cm²)/(15 cm) = 7 cm
The area of the base is then B = s² B = (15 cm)² = 225 cm²
The volume of the prism is the product of its base area and height. V = Bh V = (225 cm²)×(7 cm) = 1575 cm³
E to F = 678.35 miles F to G = 156.8 miles G to H = x Total distance = 2,457 miles E to G = 678.35 + 156.8 miles E to G = 835.15 G to H = 2,457 - 835.15 G to H = 1621.85 miles
