Cuboid

The volume of the cuboid is 245 cm3. Each cuboid edge length can be expressed by a integer greater than 1 cm. What is the surface area of the cuboid?

Correct result:

S =  238 cm2

Solution:

V=abc=245 245=5 7 7=5 72 a=5 b=7 c=7 S=2 (a b+b c+a c)=2 (5 7+7 7+5 7)=238 cm2



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
