Jason is covering an ottoman with fabric. The ottoman is in the shape of a rectangular prism that is 37 cm long, 21 wide, and 30 cm high. How much fabric is needed to cover the sides and top of the ottoman? Explain your strategy.

Respuesta :

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 cm
²

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
