Answer:
Surface Area = 214 cm^2
Step-by-step explanation:
A right Rectangular prism is gotten by adding the products of all it's sides.
That is to say, the products of it's length and width; width and height; length and health.
The formula is expressed as:
S.A = 2lw + 2wh + 2lh
= 2( lw + wh + lh).
From the Question:
Length (l) = 5cm
Width (w) = 6cm
Height (h) = 7cm
Surface Area (S.A) = 2(5*6 + 6*7 + 5*7)
S.A = 2( 30 + 42 + 35)
S.A= 2(107)
S.A = 214 cm^2
