Finding Lateral Area.

[ninax3]

Pipe organs often have large wooden pipes shaped like long, narrow boxes without bases. One of the largest organ pips, in Liverpool Cathedral, England, is about 36 ft. long, 2 ft 9 in. wide, and 3 ft 2 in. deep. Find the lateral area.


I somehow got 3241590 feet, but I think it's wrong. Does anybody know how to do this? Thanks.

How can you "think it's wrong" and not manage to produce some other response?

Convert everything to feet.

2 ft 9 in ==> 2 + 9/12 = 2.75
3 ft 2 in ==> 3 + 2/12 = 3.166666666666666666 Round it to something useful

Lateral Surface Area

2*36*2.75 =
2*36*3.17 =

Sorry. I converted it into inches & I multiplied something wrong.
But thanks!

You can use inches if you like, but that certainly makes your life more difficult.

Do the multiplications correctly and report your results.
