Question

follow the steps to find the surface area of the rectangular prism. what is the area of the top and bottom? top and bottom: ?

Explanation:

Step1: Find the area of one top or bottom face

The formula for the area of a rectangle is \(A = l\times w\). For the top/bottom face of the rectangular prism, \(l = 10\space cm\) and \(w=12\space cm\). So, \(A_{one - face}=10\times12 = 120\space cm^{2}\)

Step2: Calculate the area of top and bottom faces

Since there are 2 faces (top and bottom), \(A_{total}=2\times A_{one - face}\). Substitute \(A_{one - face}=120\space cm^{2}\) into the formula. \(A_{total}=2\times120=240\space cm^{2}\)

Answer:

\(240\space cm^{2}\)
