Question 1071347: 1. 3 gal 1 qt - 2 qt 1 pint =
2. a= 1/2h(B+b)= a=27, B=2 b=7
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! Convert everything to pints is one approach
1 gallon=4 quarts=8 pints
3 gallons=24 pints+2 pints (1 quart)=26 pints
2 quarts=4 pints+1 pint=5 pints
26-5=21 pints
That is 2 gallons (16), 2 quarts (4), 1 pint
----------------------------
======3 gal======1 qt========0 pt
minus===========2qts========1 pt
borrow
=====2 gal 3 qts-2 pints
now have 2 gal=====4 qts=======2 pt
================2 qts=======1 pt
========2 gal=====2 qts=======1 pt
====================================
a= 1/2h(B+b)= a=27, B=2 b=7
27=(1/2)h(2+7)
54=h(9), multiplying by 2
h=6
(Area of a trapezoid, finding the height)
