The dimensions of a rectangular prism are shown.

Which three statements are true about the rectangular prism?

• The base of the prism is a rectangle.

• The lateral surface area can be found using the equation.

  �=(2×19+2×5)×6S=(2×19+2×5)×6

• 
• In a rectangular prism, the total surface area can be equal to the lateral surface area

• The total surface area can be found by finding the area of each face and base and multiplying them together.
