What is the sum when the surface area of a cube whose edge measures 5 cm is added to the surface area of a sphere whose radius is 6 cm?

Sagot :

Answer:

The total surface area of cube is 150 cm2.

Answer:

What is the sum when the surface area of a cube whose edge measures 5 cm is added to the surface area of a sphere whose radius is 6 cm?

Surface Area of Cube= 6a² = 6(5)² = 6(25) = 150

Surface Area of Sphere = 4πr² = 4π(6)² =4π(36) = 144π = 452.4

∴ Sum of Surface Area of Cube + Surface Area of Sphere:

150+452.4 = 602.4cm     →Ans.
