Question

Find the surface area of the rectangular prism with 1 = 15.5 m, w = 16.5 m, and h = 4,5 m. 575.4 m2 b ос Od 2 2,301.75 m 73 m2 799.5 m2

Answer 1

Given the dimension of rectangular prism are:

Length = L = 15.5 m

Width = W = 16.5 m

Height = H = 4.5 m

The surface area of the rectangular prism =

$\begin{gathered} 2LW+2(L+W)\cdot H \\ =2\cdot15.5\cdot16.5+2\cdot(15.5+16.5)\cdot4.5 \\ =511.5+2\cdot32\cdot4.5 \\ =511.5+288 \\ =799.5 \end{gathered}$

So, the answer is 799.5 square meters
