Answer 1

Answer:

$\bf \: volume \: of \: cube = {40}^{3} = 64000 {m}^{2} \\ \\ \bf \: volume \: of \: cylinder = \pi {r}^{2} h \\ \\ \bf \implies \: 3.14 \times 20 \times 20 \times 50 = 62800 {cm}^{3} \\ \\ \bf \: volume \: of \: the \: whole \: solid \\ \\ \bf \: = 64000 - 62800 \\ \\ = \underline{ \underline{ \boxed{ \bf \mathfrak{\blue{1200 {cm}^{3}}}}}} \\ \\ \bf \: surface \: area \: of \: cube \\ \\ \bf \: = 6{a}^{2} \\ \\ \bf = 6 \times 40 \times 40 \\ \\ \bf \: 9600 {cm}^{2} \\ \\ \bf \: surface \: area \: of \: cylinder \\ \\ \bf \: = 2\pi r(h + r) \\ \\ \bf = 2 \times 3.14(50 + 20) \\ \\ \bf = 2 \times 3.14 \times 70 = 439.6 {cm}^{2} \\ \\ \bf \: surface \: area \: of \: the \: whole \: solid \\ \\ \bf \implies \: 9600 - 439.6 \\ \\ \bf \implies \underline{ \underline{ \boxed{ \mathfrak{ \green{9160.4 {cm}^{2} }}}}}$

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

1 week = 7 days

So 1 week = 7 days = 7×(24 hours) = 7×(24×(60 minutes)) = 7×(24×(60×(60 seconds))). The number of seconds in a week is 7×24×60×60. If you have a calculator on hand, you can check in a few seconds that this equals 604800. In scientific notation, this equals 6.048×105
