6. Surface Area L W 2 2lw

7. Surface Area LH 2 2lh

8. Surface Area WH 2 2wh

9. Surface Area 2lw + 2lh + 2wh TO SOLVE: 1.Plug in all #s 2.Multiply 3.Add R e m e m b e r t o s q u a r e t h e u n i t s o n y o u r a n s w e r ! Simplify formula S.A. = 2(lw + lh + wh)

10. Let’s Try One Together 1.Plug in all #s 2.Multiply 3.Add 4.Multiply 5.Final Answer S.A. = 2(lw + lh + wh) S.A. = 2(15x5 + 15x10 + 5x10) = 2(75 + 150 + 50) = 2(275) = 550

11. Try One Alone 15in 2in 8in S.A. = 2(lw + lh + wh) 1.Plug in all #s 2.Multiply 3.Add 4.Multiply 5.Final Answer = 2(8x2 + 8x15 + 2x15) = 2(16 + 120 + 30) = 2(166) = 332
