Hey mate!
Formulae of mensuration for class 8 are as follows -
Perimeter of square=4×side
Area of square=side×side
total surface area of cube=6a^2
Curved surface area of cube=4a^2
volume of cube=a^3
total surface area of cuboid=2 (lb+bh+hl)
Curved surface area of cuboid=2 (l+b)×h
volume of cuboid=l×b×h
total surface area of cuboid=2
r(r+h)
Curved surface area of cuboid =2rh
volume of cuboid=
r^2 h
Hope it helps!

Answer:
1. volume of cuboid =length *breath *height cute units.
2. Diagonal of cuboid = √(L squre +breath square + height square) units.
3. Total surface area of cuboid = 2(lb+bh+lh) sq units.
4. Lateral surface of cuboid = [2(l+b)*h] sq units.
5. Volume of cube = (side )cube cu units.
6. Diagonal of cube = √3side units
7. Total surface area of cube = 6*(side)square sq units.
8. Lateral surface area of cube= 4 (side) square squints.
