The general scientific form = a * $10^{k}$

$(6.67 * 10^{-11} )(5.97 * 10^{24} )(6.38 * 10^{6} )^{2}$

=> $(6.67 * 10^{-11} ) (5.97 * 10^{24} )(6.38 * 10^{6}) (6.38 * 10^{6} )$

= $1620.845138 * 10^{-11+24+6+6}$

= $1620.845138 * 10^{25}$

= $1.620 * 10^{28}$

hence , a = 1.620 and k= 28

$280

Step-by-step explanation:

First we need to find the volume of the dirt that is to be hauled away.

We want it in yard ^3

length =42/3 = 14 yard

width =21/3 = 7 yards

height = 6/3 = 2yds

V = length * width *height

= 14*7*2 = 196 yd^3

To find how many truck loads, divide by 7 cubic yds per truck

196 /7 = 28

We will need 28 truck loads

At 10 dollars per truckload

28*10 = 280
