Question

find the ratio of lateral surface area to the total surface area of a cube with the certain given edge

Answer 1

Csa of cube=4a^2

Tsa of cube=6a^2

Ratio of CSA:TSA=4a^2:6a^2

=4:6=2:3

Answer 2

hello friend ,
----Here is your answer---


formulas of lateral surface area & total surface area of cube with side 'a'
LSA =
$4 {a}^{2}$
TSA=
$6 {a}^{2}$
so ratio of
$\frac{l \: s \: a}{t \: s \: a} = \frac{4 {a}^{2} }{6 {a}^{2} }$
$\: \: \: = \frac{2}{3}$
ratio = 2:3
