Question

The volume of Venus is on the order of 1021 m3. (a) What is this in cubic kilometers (km3)? km3 (b) What is it in cubic miles (mi3)? mi3 (c) What is it in cubic centimeters (cm3)? cm +

Answer 1

a)1m=km

10-

1$m^{3}$=
10-
k$m^{3}$

1021
$m^{3}$=
1021
x
10-
=$10^{12}$k$m^{3}$

That is volume in cubic kilometre=$10^{12}$k$m^{3}$

b)1km=0.62mile

1k$m^{3}$=$.62^{3}$$mi^{3}$

$10^{12}$k$m^{3}$=$10^{12}$x $.62^{3}$ $mi^{3}$=0.238x$10^{12}$$mi^{3}$

Volume in cubic mile=0.238x$10^{12}$$mi^{3}$

c)1m=100cm

1$m^{3}$=
106
$cm^{3}$

1021
$m^{3}$=
1021
x
106
=$10^{27}$$cm^{3}$

Volume in cubic centimeter=$10^{27}$$cm^{3}$
