Question

If the lateral surface area of a cube is 784 cm2 and surface area of cube is equal to surface area of cuboid, then find the surface area of cuboid.​

Answer 1

Answer:

1176 cm^2

Step-by-step explanation:

as lateral surface area of cube is equal to 4a^2 therefore,

784 = 4a^2

784/4= a^2

a^2= 196

a=14

now as we know that surface area of cube is equal to 6a^2 and according to question it is equal to the surface area of cuboid therefore,

6a^2 = 6 × 14^2

= 6× 196

= 1176 cm^2
