Answer:

The volume of water in water bath is 1,011 Liters.

Explanation:

Length of the water bath, L = 1.85 m

Width of the water bath, W= 0.810 m

Height of the water bath ,H= 0.740 m

Height of the water in water bath, h= 0.740 m - 2.57 inches

1 m = 39.37 inch

$= 0.740 m - \frac{2.57}{39.37} m = 0.6747 m$

Volume of the water in bath = L × W × h

$=1.85 m\times 0.810 m\times 0.6747 m=1.011 m^3$

$1 m^3=1000 L$

$1.011 m^3=1.011\times 1000 L=1,011 L$

The volume of water in water bath is 1,011 Liters.

PLEASE HELP<br><br> (1.1232 x 10^5)(6.022 x 10^17).

omeli [17]

(1.1232 * 10⁵) (6.022 * 10¹⁷)

Now, multiply simple numbers together and exponentials, together:
= 1.1232 * 6.022 * 10⁵ * 10¹⁷
= 6.763 * 10²²

In short, Your Answer would be 6.763 * 10²²

Hope this helps!
