Answer:
Step-by-step explanation:
First, lets simplify everything in the parenthesis.
(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:
6*10^-2
Or
.06
Since A=l*w*h,
A=4.5*7.25*6.5
A=212.0625
A=212.0 feet squared is the answer.
He needs 2.5 lbs of sugar and 2.5 lbs of water
