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.
Calculations for a rectangular prism: 1. Given the length, width and height find the volume, surface area and diagonal of a rectangular prism. 1  h, l and w are known; find V, S and d. 2  V = lwh. 3  S = 2(lw + lh + wh). 4  d = â(l 2 + w 2 + h 2).. Given the volume, length and width find the height, surface area, and diagonal of a rectangular prism. 1  V, l and w are known; find h, S and d. 2  h = V / lw. 3  S = 2(lw + lh + wh).
