find the CSA and TSA of the cube whose sides
are
a = 7.5cm​

Answer 1

Answer:

Hello

Step-by-step explanation:

Here's your answer Check it.

CSA = 4 (7.5) (7.5) = 4 × 56.25

. = 225 cm²

TSA = 6 (7.5) (7.5) = 6 × 56.25

. = 337.5 cm²

Answer 2

$\huge \red{ \rm{ Answer \: } \dag : }$

Given :

➡a = 7.5 cm

$\huge \rm \underline \red{Formulae \: Used} \dag$

$\large \mathbb{\boxed {CSA \: of \: square \: =4 \: { \: a}^{ \: 2} }}$

$\large \boxed{TSA \: of \: square = 6 {a}^{2} }$

CSA = 4 (7.5) (7.5) = 4 × 56.25

. = 225 cm^2

TSA = 6 (7.5) (7.5) = 6 × 56.25

. = 337.5 cm ^2
