Question

Maths formula of class 9th icse,chapter 21(solids) give me full nd complete formula plz as soon as possible plz....plz as a correct ans plz ful formula of math, icse​

Answer 1

Answer:

Cuboid:-

Volume=length×breadth×height (or) l×b×h.

Total Surface Area(TSA)=2(l×b+b×h+h×l).

Lateral Surface Area(LSA)=2(l×b)×h.

Length of diagonal=√l²+b²+h².

Cube:-

Volume=a² (or) (edge)².

Total Surface Area(TSA)=6a².

Lateral Surface Area(LSA)=4a².

Length of diagonal=a√3. (or) √a²+a²+a².

I think this is your answer.
