Question

1. Find the side of a cube whose lateral
surface area is 144 cm2.​

Answer 1

Answer:

see,

Step-by-step explanation:

there are 6 sides of cubes so divide 144 with 6 and you will get the answer 24

Answer 2

Correct Question:

$\sf{Find \: the \: side \: of \: a \: cube \: whose \: lateral \: surface \: area \: is \: {144cm}^{2} }$

Given:

Lateral Surface Area Of Given Cube Is $\sf { {144cm}^{2} }$

Solution:

$\sf {lateral \: surface \: area \: of \: a \: cube \longmapsto {4a}^{2} } \\ \sf { \longmapsto144 = {(4 \times a)}^{2} } \\ \\ \sf{\longmapsto 144 = 16a} \\ \\ \sf{\longmapsto \frac{144}{16} = a} \\ \\ \sf{ \longmapsto \cancel \frac{144}{16} \: \: ^{9} = a} \\ \\ \sf{\longmapsto9cm}$

To Know More! :

$\sf\longmapsto {cube \: is \: a \: 2nd \: form \: of \: square} \\ \longmapsto\sf{perimeter \:of \: square \: is \: 4 \times side } \\ \longmapsto\sf{area \: of \: Square \: is \: side \times side} \\\longmapsto \sf{total \: surface \: area \: of \: cube \: is \: {6a}^{2} }$
