Answer:

I. Base area = 35 cm²

II. Volume of rectangular prism = 350 cm³

Step-by-step explanation:

Given the following data;

Length = 7cm

Breadth = 5cm

Height = 10cm

a. To find the base area of the rectangular prism;

Base area = length * breadth

Base area = 7 * 5

Base area = 35 cm²

b. To find how much it takes to fill the rectangular prism, we would need to determine its volume.

Volume of rectangular prism = length * breadth * height

Volume of rectangular prism = 7 * 5 * 10

Volume of rectangular prism = 350 cm³

c. To find the answers to the other part of the question, we would determine the capacity of the prism in litres.

Capacity = volume in cm³ to litres

1 centimeter = 0.001 litres

Capacity = 350 * 0.001

Capacity = 0.35 litres.

Bob's Skate Shop had a profit of $3,563 during the month of August. The company models its profit using p=x^2+10x-12 where x is

I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.
