Answer 2

Answer: 94 cm2

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

A = 2wl +2 lh+2hw

Where:

A = surface area of a prism

w = width

l= Length

h =height

Replacing with the values given and solving:

A = 2(4x5) +2 (5x3)+2(3x4)

A = 2(20) + 2(15)+ 2(12)

A= 40+30+24

A= 94 square centimeters
