Plz help I have tried but got wrong
Lapatulllka [165]

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.

Your making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much salt is needed
Citrus2011 [14]

We can make this into a ratio of salt:baking soda

1/8:1/4

now, how many 1/4 will we need to make 1?

If we multiply 1/4 by 4, we get one. So, we should do the same to 1/8!

1/8*2=4/8, or 1/2 teaspoon
