Answer:
Step-by-step explanation:
we know that
we need to calculate the surface area including only one base
surface area=area of the base+perimeter of the base*height
area of the base=37*21----> 777 cm²
perimeter of the base=2*[37+21]----> 116 cm
height of the prism=30 cm
surface area=777+116*30-----> 4257 cm²
the answer is
4257 cm²
