Answer 1

The surface area of Rectangular prism is
`358 \ cm^2`.

Explanation:

Given:

Length of the rectangular prism = 7 cm

Width of the rectangular prism = 5 cm

Height of the rectangular prism = 12 cm

we need to find the surface area of rectangular prism.

Solution:

the surface area of rectangular prism is equal to 2 times sum of length times width and width times height and length times height.

framing in equation form we get;

the surface area of rectangular prism =
`2(l* w+w* h+h* l)`

the surface area of rectangular prism =
`2(7*5+5*12+12*7) = 2(35+60+84) = 2*179 = 358\ cm^2`

Hence The surface area of Rectangular prism is
`358 \ cm^2`.
