Weegy: The formula for the volume of a square pyramid is: 1/3bh^2. So: 1/3(14)(18^2) V = 1512 feet cubed User: Find the lateral area of a triangular prism with base edges of 5cm, 12cm, and 13 cm. The height of the prism is 14cm. Weegy: The lateral area is the perimeter of the base times the height, (5 + 12 + 13)(14). I'll let you do the arithmetic.
BTW this is just the sum of the areas of 3 rectangles that form the sides of the prism: ... (More)
