Answer 2

Answer :-

• TSA of the Cube = 337.5 cm²

• LSA of the Cube = 225 cm²

Given :-

• Edge of Cube = 7.5 cm

To Find :-

• TSA of the Cube = ?

• LSA of the Cube = ?

Explanation :-

As we know,

• Total Surface Area (TSA) :- The area of body of a 3-D shape including it's base and top.
• Lateral Surface Area (LSA) :- The area of body of a 3-D shape excluding it's base and top.

$\underline { \boxed { \bf \implies TSA \: of \: Cube = 6(Edge)^2 }}$

$\underline { \boxed { \bf \implies LSA \: of \: Cube = 4(Edge)^2 }}$

Now Substituting the values,

➠ Finding TSA of Cube

$\rm \implies TSA \: of \: Cube = 6(Edge)^2$

$\rm \implies 6(7.5)^2$

$\rm \implies 6(56.25)$

$\rm \implies 6 \times 56.25$

$\underline { \boxed { \bf \implies 337.5 \; \; cm^2}}$

➠ Finding LSA of Cube

$\rm \implies LSA \: of \: Cube = 4(Edge)^2$

$\rm \implies 4(7.5)^2$

$\rm \implies 4(56.25)$

$\rm \implies 4 \times 56.25$

$\underline { \boxed { \bf \implies 225 \; \; cm^2}}$

Hence, the TSA and LSA of the Cube are 337.5 cm² and 225 cm² respectively.
