Answer:
the surface area of the right rectangular prism is, \(1205.62 cm^2\)
Step-by-step explanation:
Surface area of the right rectangular prism(S) is given by:
\(S=2(lw+wh+hl)\) ....[1]
where
l is the length , w is the width and h is the height of the rectangular prism.
As per the statement:
A right rectangular prism has a length of 20.2 cm, a width of 9.1 cm and a height of 14.3 cm.
⇒ l = 20.2 cm , w = 9.1 cm and h = 14.3 cm
Substitute these in [1] we have;
\(S = 2(20.2 \cdot 9.1+9.1 \cdot 14.3+14.3 \cdot 20.2)\)
⇒\(S = 2(183.82+130.13+288.86) = 2(602.81) = 1205.62 cm^2\)
therefore, the surface area of the right rectangular prism is, \(1205.62 cm^2\)
