Question

The edge of a cube is a/2 cm. The volume of cube is: a. a 3 cm 3 b. a 3 /2 cm 3 c. a 3 /8 cm 3 d. 3a /2 cm​

Answer 1

Given,

edge of a cube is a/2 cm .

find the volume of cube .

Solution :

let's solve this by using

$\underline{ \boxed{ \color{gold} \bf{volume = {(edge)}^{3} }}}$

then on substituting the values,

$\rm⇢ \: \: {( \frac{a}{2} )}^{3}$

$\rm⇢ \: \: volume = \frac{ {a}^{3} }{8} \: cm ^{3}$

FINAL ANSWER :

Volume of the cube is a³/8 cm³ .

hence, option c is the correct answer .

Answer 2

Answer:

a 3cm is the correct answer
