Question

Find the lateral surface area and total surface area of a dice having 12cm length

Answer 1

Step-by-step explanation:

We Have :-

$Dice \: of \: edge \: length \: 12 \: cm$

To Find :-

$LSA \\ \\ \\ TSA$

Formula Used :-

$LSA \: of \: cube \: = \: 4 \times side^{2} \\ \\ \\ TSA \: of \: cube \: = \: 6 \times side^{2}$

Solution :-

$We \: have \: side \: = \: 12 \: cm \\ \\ \\ LSA \: of \: cube \: = \: 4 \times side^{2} \\ \\ \\ LSA \: of \: cube \: = \: 4 \times (12)^{2} \\ \\ \\ LSA \: of \: cube \: = \: 4 \times 144 \\ \\ \\ LSA \: of \: cube \: = \: 576 \: cm ^{2} \\ \\ \\ \\ TSA \: of \: cube \: = \: 6 \times side^{2} \\ \\ \\ TSA \: of \: cube \: = \: 6 \times (12)^{2} \\ \\ \\ TSA \: of \: cube \: = \: 6 \times 144 \\ \\ \\ TSA \: of \: cube \: = \: 864 \: cm^{2}$
