Answer:
1. 9 * 5 in.
2. 3 * 15 in.
Step-by-step explanation:
Volume = 1/3 * area of the base * height
120 = 1/3 * A * 8
So A = 120 / (8/3)
= 120 * 3/8
= 45 in^2.
So the dimensions of the base could be 9 * 5 in
or 3 * 15 in.
Simply simplify multiplication expressions with a positive exponent
$54.29
This is because 5% of $51.70 is $2.59. The sum of the tax and bill would become $54.29.
