Tommy has right rectangular prism with base length 5 and a cylinder with radius 2.5. If both objects have equal surface areas, what is :

a)the height of the right rectangular prism?
b) the height of the cylinder?
Use Pi =3.14

1 answer

if the prism is axbxc, the the surface area is 2(ab+ac+bc). Let a=5. Then

area = 2(5b+5c+bc)

area of cylinder = 2pi(r^2+h) = pi(6.25+h)

Sure there's not more info? There are too many unknowns above.
