Calculating Surface Area of Rectangular Prisms

What does surface area of a 3D object represent?

• The sum of the areas of all the faces of the object

• The length of the object

• The perimeter of the object's base

• The volume inside the object

What is the shape of each face of a rectangular prism?

• Triangle

• Square

• Circle

• Rectangle

How many faces does a rectangular prism have?

• Eight

• Six

• Ten

• Four

If one side of a rectangular prism is 10 by 6 cm, what is its area?

• 16 cm²

• 60 cm²

• 100 cm²

• 30 cm²

What is the area of a rectangle with dimensions 4 cm by 6 cm?

• 24 cm²

• 10 cm²

• 20 cm²

• 12 cm²

How can you calculate the total surface area of a rectangular prism?

• Add the area of each side

• Add the volume of all sides

• Subtract the smallest area from the largest

• Multiply the area of one side by six

What simplifies the calculation of surface area for symmetrical shapes like rectangular prisms?

• Using a net

• Ignoring the dimensions

• Only calculating one side

• Estimating the area

When identical sides are present, how can you simplify the calculation of total surface area?

• Divide the area of one side by two

• Multiply the area of one side by the number of identical sides

• Add the areas of all sides

• Calculate the area of one side only

What is the total surface area of a rectangular prism if the areas of its sides are 60, 40, and 24 cm² respectively?

• 204 cm²

• 124 cm²

• 180 cm²

Which method allows for easier calculation of surface area when dealing with complex shapes?

• Using a net and calculating each side

• Ignoring smaller sides

• Using a single formula

• Estimating visually
