Today in class we learned how to calculate the surface area of composite shapes and the surface area of my shape was 1150 cm 2.

Today in class we learned how to make nets using the circufamce, radius, diameter and side lengths. We all made hockey pucks and these are the steps how to make a paper hockey puck.

Today in clas we learned about surface area and volume. The difference between surface area and volume is that surface area is the sum of all the faces on an object. Volume is the amount of space an object occupies.

1A) S.A.= (12×2)+(8×2)+(6×2)=52 U 2

1B) S.A. = (6×2)+(8×2)+(16)+(20)= 64 U 2

1C) S.A. = (8×2)+(4×5)+(6)+(2) = 44 U 2

1D) S.A. = (8×2)+(6×2)+(8)+(4×3)+(4) = 52 U 2

2A) S.A. = (24×2)+(16×2)+(12×2) = 104 U 2

2B) S.A = (6×2)+(16×4) = 76 U 2
