Volume and Surface Area of Prisms

The video tutorial covers lesson 25 on volume and surface area, focusing on real-world examples like fish tanks. It explains how to calculate the volume and surface area of a right rectangular prism, using a fish tank as an example. The tutorial also includes exercises comparing different tank designs, emphasizing the importance of understanding these concepts in practical scenarios.

What is the formula for calculating the volume of a right rectangular prism?

• Length + Width + Height

• Length x Width x Height

• Length x Width + Height

• 2 x (Length + Width + Height)

How do you calculate the surface area of a right rectangular prism?

• Add the areas of all the faces

• Multiply the length by the width

• Subtract the volume from the area

• Divide the volume by the height

How many square inches are needed to cover the back, left, and right sides of the fish tank?

• 400 square inches

• 180 square inches

• 300 square inches

• 240 square inches

How much water evaporates when the water level drops to 4 inches deep?

• 3 gallons

• 2.5 gallons

• 1.39 gallons

• 0.5 gallons
