Question

The total surface area of a cubical chocolate box is 150 cm³, find its lateral surface area

Answer 1

Answer:

Step-by-step explanation:

Given volume=150 cm3

Let side be x

Volume =x3

150=x3

3√150=x

3×3.5=x

X=10.5

Side =10.5

Now, lsa =4×10.5

=42cm2

Answer 2

Answer:

Formula of surface area of cube : 6 L ^ 2

6 L ^ 2 = 150

L ^ 2 = 150/6

L ^ 2 = 25

L = √25

L = 5

So now we are going to find the lateral surface area

Formula = 4 L ^ 2

4 x 5 x 5

= 100

So, the lateral surface area of the cube will be 100
