Quiz-7th Grade Geometry!(Formulas) 5/26/22

Question 1

Volume of Rectangular Prism=

Answer 1

V = l x w x h

Question 2

Volume of Triangular Prism=

Answer 2

V = Bh OR V = 1/2 l x w x h

Question 3

Volume of Pyramid =

Answer 3

V = 1/3 B x H (1/3 x area of base x height of pyramid)

Question 4

Surface Area of Rectangular / Triangular Prism=

Answer 4

SA = Ph + 2B (perimeter of base x height + 2x the area of the base)

Question 5

Surface Area of Pyramids =

Answer 5

SA = 1/2 P(Perimeter of base) x l (Slanted height) + B (Area of Base) or SA = LA+B

Question 6

Slanted Height

Answer 6

Height of the lateral face
