The district serves 10,400 students and operates 15 schools: one high school â William Penn (grades 9-12), three middle schools (grades 6-8), four intermediate schools (grades 3-5), six primary schools (K-2), and one school for physically challenged students at all grade levels.
How to Find the Volume of a Rectangular Prism. A rectangular prism has three dimensions: length (l), width (w), and height (h). A rectangular prism has volume formula V = lwh. So, for example, if a rectangular prism has dimensions l = 12 in., w = 4 in., and h = 3 in., then V = 12 in. x 4 in. x 3 in.
A right-angled triangular prism is called a right prism. The formula for calculating the volume of a prism is V = B x h, where B = area of base, and h = height of the prism. Tâ¦he area for the base is calculated using the formula B = 1/2(length x height) (area of a triangle). Example: The height of a prism is 10 cm.
