### PowerPoint Presentation:

A cube is a three dimensional shape that features all right angles and a height, width and depth that are all equal. A cube has 6 square faces, 8 points (vertices ), 12 edges, 12 face diagonals, and 4 space diagonals

### PowerPoint Presentation:

M-E-A-S-U-R-E Feet, Inches, Meter, Centimeter That’s the way we name it The units we see along the way Com’n everyone and let us! M-E-A-S-U-R-E! (3x) Because i t is Fun! (2x) sing with us

### PowerPoint Presentation:

At the end of the lesson the pupils will be able to: Familiarize the formula of Surface Area and Volume. Use the formula in measuring a cube. Answer and solve problems involving cube.

MEASURING A CUBE

### PowerPoint Presentation:

formula SURFACE AREA Surface Area= 6s 2 / SA=6s 2 VOLUME Volume=s 3 / V= s 3

### PowerPoint Presentation:

Surface area Given: s= 6 m Find: SA=? SA=6s 2 SA= 6 (6) 2 SA= 6 (36) SA= 216 m 2 Given: s= 4 m Find: SA=? SA=6s 2 SA= 6 (4) 2 SA= 6 (16) SA= 96 m 2

### PowerPoint Presentation:

VOLUME V= s 3 V= (7) 3 V= 343 m 3 Given: s= 7 m Find: V=? Given: s= 5 m Find: V=? V= s 3 V= (5) 3 V= 125 m 3

### PowerPoint Presentation:

Given: s=12 m Find: SA=? Given: s=24 m Find: SA=? Given: s=18 m Find: V=? Given: s=22 m Find: V=? Group 1 Group 3 Group 2 Group 4

### PowerPoint Presentation:

Group 1 SA =6 s 2 SA= 6 (12) 2 SA= 6 (144) 2 SA= 864 m 2 Given: s= 12 m Find: SA=?

### PowerPoint Presentation:

Group 2 V= s 3 V= (18) 3 V= 5,832 m 3 Given: s= 18 m Find: V=?

### PowerPoint Presentation:

Group 3 SA = 6s 2 SA= 6 (24) 2 SA= 6 (576) 2 SA= 3,456 m 2 Given: s= 24 m Find: SA=?

### PowerPoint Presentation:

Group 4 V= s 3 V= (22) 3 V= 10, 648 m 3 Given: s= 22 m Find: V=?

### PowerPoint Presentation:

Quick quick Game!

### PowerPoint Presentation:

Rona measured her Rubik’s cube. Half of one of the cube edge measures 7.5 cm . Calculate the Surface Area and its Volume. V= 3,375 cm 3 SA= 1,350 cm 2

### PowerPoint Presentation:

Mang Jose cut a big cubic woods to use as mini-chair for their dining . One of the cubic wooden chair measures 24 feet on its edge. What is the Volume and Surface Area of the cubic wooden chair of Mang Jose? SA= 3,456 ft 2 V= 13,824 ft 3

### PowerPoint Presentation:

MATHEMATICS IS truly FUN!

### PowerPoint Presentation:

Answer the following s=8 m, Find the Volume S=20 ft , Find the Surface Area S=14 cm, Find the Volume S=27 cm, Find the Volume S=80 mm, Find the Surface Area GOOD LUCK 

### PowerPoint Presentation:

Assignment: Find a small cubic object in your house. Measure its edge and calculate its Volume and Surface Area. Write it on a ½ sheet of paper
