3-D Shapes Surface Area and Volume

What is total surface area?

• The sum of the surface areas of all its faces excluding the bases of the solid.

• The sum of the surface areas of all the faces of the solid.

________ is the amount of space inside of a 3D shape.

• Surface Area

• Volume

If the radius of a cylinder is 4cm and height is 10cm, then total surface area of cylinder is:

• 440 sq.cm

• 352 sq.cm.

• 400 sq.cm

• 412 sq.cm

The length, breadth and height of a room are 12 m, 10 m, and 9m respectively. Find the area of four walls of room?

• 636 m²

The length of the base of a box is (x-3), and the width is (x+2). The height is two more than three times the length. Build a function to model the volume of the box.

• (x-3)(x+2)(3x+2)

• (x-3)(x+2)(3x-7)

• (x-3)(x+2)(3x+9)

• (x-3)(x+2)(3x-1)
