What is the surface area of this right rectangular prism? Enter your answer in the box. cm² A rectangular prism with a length of 5 centimeters, a width of 4 centimeters, and a height of 7 centimeters.

we know that
surface area of the prism=2*area of the base+perimeter of the base*height

step 1
find the area of the base
area of the base=length* width
length=5 cm
width=4 cm
area of the base=5*4-----> 20 cm²

step 2
find the perimeter of the base
perimeter=2*[length+width]-----> 2*[5+4]----> 18 cm

step 3
height=7 cm

step 4
find the surface area
surface area of the prism=2*area of the base+perimeter of the base*height
surface area of the prism=2*20+18*7----> 166 cm²

the answer is
166 cm²
