Question

what is the total area of a right rectangular prism with a height of 8ft, a width of 10ft, and a thickness of 12 ft.

Answer 1

Let's begin by listing out the information given to us:

This is a rectangular prism

Height (h) = 8 ft, Width (w) = 10 ft, Thickness (l) = 12 ft

The total area of a right rectangular prism is given by:

$\begin{gathered} A=2\mleft(wl+hl+hw\mright) \\ A=2(10\cdot12+8\cdot12+8\cdot10) \\ A=2(120+96+80) \\ A=2(296) \\ A=592ft^3 \end{gathered}$
