Formula for volume of cuboid​

Cube                                 Cuboid

Volume of cube = (Side)3Volume of the cuboid = (length × breadth × height)

Diagonal of a cube = √3lDiagonal of the cuboid =√( l2 + b2 +h2)

Perimeter of cube = 12 x sidePerimeter of cuboid = 4 (length + breadth + height)

Step-by-step explanation:

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
