Question

find the volume, the total surface area, the lateral surface area and diagonal of cube whose edge is 9.75cm​

Answer 1

Answer:

these questions is very hard I can't to solve the problem

Answer 2

Answer:

do same as below

Step-by-step explanation:

It is given that each edge of a cube = 9m We know that Volume of cube = a3 By

substituting the values

Volume of cube = 93

So we get Volume of cube = 729 m3

We know that Lateral surface area of cube = 4a2

By substituting the values

Lateral surface area of cube = 4 × 92 So we get Lateral surface area of cube = 4 × 81 = 324 m2

We know that Total surface area of cube = 6a2

By substituting the values

Total surface area of cube = 6 × 92 So we get Total surface area of cube = 6 × 81 = 486 m2 We know that Diagonal of cube = √3 a

By substituting the values Diagonal of cube = 1.73 × 9 = 15.57 m

Therefore, the volume is 729 m3, lateral surface area is 324 m2,

total surface area is 486 m2 and the diagonal of cube is 15.57 m.
