Question

Determine the surface area of a rectangular prism with the following dimensions:
Length = 4 cm, Width = 2 cm, Height = 3
A.52 sq. cm
D.20 sq.cm
d. 290 sq. cm
B.104 sq.cm

Answer 1

Answer:

A. 52 sq. cm

Step-by-step explanation:

surface area of a rectangular prism = 2(LW + WH + LH)

where

L = 4cm

W = 2cm

H = 3cm

plugin values into the formula:

As = 2(4*2 + 2*3 + 4*3)

As = 52 sq. cm

Answer 2

Answer:

A.52 sq. cm

Step-by-step explanation:

Given: l = 4 cm, w = 2 cm, h = 3 cm

Surface area of a rectangular prism

=2(l*w + w*h+h*l)

= 2(4*2 + 2*3 + 3*4)

= 2(8 + 6 + 12)

= 2*26

= 52 sq. cm
