Triangular Prism

Check the prism above.

Choose the WRONG alternative.

• It is formed by triangles and rectangles

• It is called triangular prism

• Removing one triangular face it would be a pyramid

• It has 5 faces

Look at at picture. All alternatives are right, EXCEPT:

• It shows 2 equal triangles

• It shows 3 equal rectangles

• The base area of the prism it is a from rectangle

• From left to right it is showing us a NET.

One dimension (measurement) is increasing from the image above. It is the:

• Height of the base area

• Width of the triangle

• Length of the base area

• Height of the prism

The formula for finding the volume of any prism is:
Volume = base area X Height
(H is the height of the prism)
(h is the height of the triangular base)
So, if you are trying to calculate a volume of a triangular prism you will do:

•  $b\times h\times H$  

•  $\frac{b\times h}{2}\times H$  

•  $b\times h\times2\times H$  

•  $\frac{b\times2}{h}\times H$  

The image shows 2 measurements. A and B represent:

• Length of the prism and width of the triangular base

• Length of the prism and height of the triangular base

• Height of the prism and length of the triangular base

• Width of the prism and height of the triangular base

A triangular prism has base area equals 15 cm². Its length (or height) is 100 mm. Its volume is:

• 150 cm³

• 1 500 cm³

• 15 000 cm³

• 150 000 cm³

The surface area (SA) of a triangular prism means:

• 
• 
• 
• 

When we apply the formulas for calculating the surface area or the volume of a triangular prism, we use only:

• Addition and Multiplication

• Multiplication and Division

• Addition, Multiplication, and Division

• Subtraction, Multiplication, and Addition

Check the dimensions of the drawing above. The base area is equal to:

• 24 m²

• 30 m²

• 27 m²

• 48 m²

The volume of a triangular prism is 120 mm³. The base area of the triangular base is 30 mm². The height (or length) of that prism will be:

• 3.0 mm

• 4.0 mm

• 5.0 mm

• 3.5 mm
