Question

side of cube whose CSA is 36sq unit​

Answer 1

$\huge\mathfrak{\red{Answer}}$

3 units

Step-by-step explanation:

Given= L.S.A of cube = 36sq.unit

L.S.A of cube=

$4 \times (side) {}^{2}$

Now,

Let the side of cube be x units

Therefore,

$4 \times (x) {}^{2} = 36$

$= > {x}^{2} = \frac{36}{4}$

${x}^{2} = 9$

$x = \sqrt{9} = > x = 3 \: units$

Hence, the required side of the cube is 3 units.

To solve such questions, we should know the formulas like:-

• TSA of cube = 6 × side^2

• LSA of cube = 4× side^2

• Volume of cube = side^3
