Question

If the total surface area of a cune is 24cm square. find its length​

Answer 1

Answer:

Length = 2 cm

Step-by-step explanation:

Total surface area of Cube,

6a² = 24

a² = 24/6 = 4

a = √4 = 2

Length, a = 2 cm

If the total surface area of a cune is 24cm square. find its length

$\huge\color{golden}{\textbf{\textsf{ Answer:-}}}$

The length of the side of the cube is 2 cm.

Step-by-step explanation:

We have been given:

Surface area of cube=24=24 cm²

As we know:

The formula of surface area of cube=6a=6a²

Hence:

$6a ^{2} = 24 \\ a ^{2} = \frac{24}{6} \\ a {}^{2} = 4 \\ a = \sqrt{4} \\ a = 2$

Therefore the length of the side of the cube is 2 cm.
