Question

Find the length of the side of the cube whose total surface area is 600 sq.cm.

Answer 1

Ⓡⓔⓠⓤⓘⓡⓔⓓ ⓓⓐⓣⓐ

Total surface area or tsa of a cube =600cm²

we find the length of the side of the cube

in this sum we used the formula of total surface area of cube

ғᴏʀᴍᴜʟᴀ ᴏғ ᴛsᴀ ᴏғ ᴄᴜʙᴇ =6ʟ²

here total surface area =6l²=600

according to the question,

6l²=600

or,l²=600/6(dividing both sides by 6)

or,l²=100

or,√l²=√100

or,l=10

length of the side of the cube =10cm

A cube is a region of space formed by six identical square faces joined along their edges. Three edges join at each corner to form a vertex. The cube can also be called a regular hexahedron. It is one of the five regular polyhedrons, which are also sometimes referred to as the Platonic solids.
