  1. Changing attributes in Volume and Surface Area Math 8

  2. Changing height by half Find the volume of cylinder #2 if the height is half of cylinder #1. #1 #2 r = 6m r = 6m h = 18m h = V = V =

  3. Double the height • Find the volume of cylinder #2 if the height is double of cylinder #1. #2 #1 r = 8cm r = 8cm h = 10cm h = V = V =

  4. Changing one measurement by half Find the volume of prism #2 if the length, width or height is half the measurement of prism #1. #1 #2 l = 12in l = w = 10in w = h = 8in h = V = V =

  5. Double one measurement • Find the volume of prism #2 if the length, width or height is double the measurement of prism #1. #1 l = 8yd l = #2 w = 4yd w = h = 6yd h = V = V =

  6. Double all 3 measurements • Find the volume of prism #2 when all three measurements of prism #1 are doubled. #1 #2 l = 4m l = w = 2m w = h = 6m h = V = V =

  7. Half all 3 measurements Find the volume of prism #2 when all three measurements of prism #1 are divided in half. #2 #1 l = 25m l = w = 14m w = h = 18m h = V = V =

  8. Double all 3 measurements Find the surface area of a prism when all 3 measurements are doubled. #1 #2 l = 8yd l = w = 4yd w = h = 6yd h = SA = SA =

  9. Half all 3 measurements Find the surface area of a prism when all three measurements are cut in half. #1 #2 l = 16m l = w =12m w = h =10m h = SA = SA =

  10. Changing Attribute Measures for Surface Area and Volume Review • Cylinder • When you double height, double volume (multiply by 2) • When halving height, half volume (divide by 2) • Prism • When doubling length, width or height, double volume (multiply by 2) • When halving length, width or height, half volume (divide by 2) • When you double all 3 measurements, multiply the volume by 8 • When halving all 3 measurements, divide the volume by 8 • When you double all 3 measurements, multiply the surface area by 4. • When halving all 3 measurements, divide the surface area by 4.
