Exploring Volume of Composite Figures

The video tutorial explains how to find the missing length and calculate the volume of a complex shape. It begins by defining the problem and the goal of finding the volume. The process involves dividing the shape into two areas, calculating each area using parallel lines, and then combining them to find the total area. Finally, the volume is calculated by multiplying the total area by the depth. The tutorial concludes with a mention of additional resources available online.

What is the definition of volume?

• The amount of space occupied within a solid

• The perimeter of a solid

• The length of a solid

• The surface area of a solid

Why do we break the shape into two areas for calculating volume?

• To find the missing length

• To simplify the calculation by finding the area of each face separately

• To increase the accuracy of the volume calculation

• To demonstrate complex mathematical techniques

How do we find the missing length in a complex shape?

• By using the shape's perimeter

• By measuring directly

• By looking for parallel lines

• By calculating the shape's area

How do parallel lines help in finding the missing length?

• By determining the shape's area

• By showing the shape's symmetry

• By providing a direction

• By indicating equal lengths

What is the missing length if one side is 55 cm and the other is 30 cm?

• 85 cm

• 25 cm

• 55 cm

• 30 cm

How do we calculate Area 1?

• Length - Breadth

• Length / Breadth

• Length x Breadth

• Length + Breadth

What is the formula to calculate volume?

• Volume = Area of the face x Depth

• Volume = Area of the face + Depth

• Volume = Area of the face - Depth

• Volume = Area of the face / Depth

What is the total face area if Area 1 is 1,500 cm² and Area 2 is 600 cm²?

• 2,100 cm²

• 1,100 cm²

• 900 cm²

• 2,000 cm²

What is the depth of the shape if all sides marked are 12 cm?

• 18 cm

• 12 cm

• 6 cm

• 24 cm

What is the volume of the shape if the total face area is 2,100 cm² and the depth is 12 cm?

• 25,200 cm³

• 2,112 cm³

• 1,200 cm³

• 2,100 cm³
