Question

tha surface area of the cube whose edge equal to 3 cm​

Answer 1

Answer:

$surface \: area \: of \: cube \: = \: 6 {a}^{2} \\ = 6 \times {3}^{2} \: \: \: \: \: \\ = 6 \times 9 \\ \: \: \: \: = 54 {cm}^{2} \\ \\ hope \: itz \: help \: u...$

Answer 2

Answer:

$384 cm^2$

Step-by-step explanation:

surface area of a cube = $6a^2$

where "a" is the edge of the cube

edge(a) = 3 cm

now apply the formula, $6a^2$

$6$ × $8^2$

= $384 cm^2$

Hence, the surface area of the cube = $384 cm^2$

Few more important formulas related to cubes :-

• surface area of a cube = $6a^2$
• curved surface area of a cube = $4a^2$

• volume of a cube = $a^3$

where "a" is the edge of the cube
