<PRE><B>Question 258568</B>
If a block of ice measures 24 in. x 36 in. x 18 in.
----------------
1 inch is 2.54 cetimeters
1 cm = 0.01 meter
------------------------------------
24 in = 24*2.54 cm = 60.96 cm = 0.6096 meters
36 in = 36*2.54 cm = 91.44 cm = 0.9144 meters
18 in = 18*2.54 cm = 45.72 cm = 0.4572 meters
=---------------------------------------

(a) What is the volume of this block in cubic meters?
Volume = the product of the meter measures = 0.25485 cu meters
-----------------------------------------------------------------------

(b) What is the total surface area of the block in square centimeters?
surface area = 2(60.96*91.44) + 2(60.96*45.72) + 2(91.44*45.72)
= 11148.3648 + 5574.1924 + 8361.2736
= 25083.8308 sq. cm.
