Question

What is the surface area of a right rectangular prism with a length of 5 cm, a width of 6​ cm, and a height of ​7​ cm? Enter your answer in the box. The surface area is
______cm².

Answer 1

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
