  1. 8th Math 1st benchmark Review By ShahzadiAlmas

  2. Compare and Order • Coldest to warmest • Ascending order It means least to greatest. • Warmest to coldest • Descending order It means greatest to least. • Arrange: -12, -10, 1, -2, -18 • If you have all fraction, in order to compare just find out common denominator. • 7/9 closest to .50 or 1.00 • -1/2 > -2/3 • 1 and 1/3 = 4/3

  3. Rational Numbers • Add: Credit, Gain, Total • Subtract: Spent, Remaining balance, difference 0.00174 – 0.00157 = ? Above sea level-below sea level 1235 – (- 34) • Multiply and divide: • Make a T-chart • Set up as ratio • Hours lessons ½ 1 15 X

  4. Square Root • Square root of 28: • Square root of 205: Between…….and…… • Square root of 25/49: • Square root of 18: 3 4 5 6

  5. Top, Front, Side view • What is the shape of cone after cutting half horizontally and vertically? • solid

  6. Volume How many small boxes can fit into the large box? Expression. What is height? If volume is 140. • Write expression to find out the volume of cone 5 times, with radius of 2 and height is 3? • 1st rectangular prism with dimension 4 by 3 by5, and 2nd rectangular prism with dimension 3 by 3 by 5. Who has greater volume? • What is the volume of square pyramid if area of the base if 36 and height is 7?

  7. Area What is the area of new wall?

  8. Surface Area • Label of 10 cans if radius is 4 and height is 7. • How much paper is needed to decorate the box, if l=6,w=2 and h=8 ? • If perimeter is 40 and height is 5, what is the lateral surface area of pyramid? • Surface area of cane if radius is 2 and h=3.5? Expression only. • Surface area of box with no lid, l=10, w=5, h=15 Surface area: 12 8 5

  9. Dimensional changes • If each side of triangle is 2.5, what is the perimeter if each side is double? • If each side of 1st cube is a and 2nd cube is 2a, how many times surface area is bigger? • If each side of photographed measured 6 by 12 is reduced to half, what is the area of new photograph? • Dimension of triangular prism is doubled, multiply by what …………..? • If scale factor is half, volume is reduced by…………… • V = 2400, and scale factor is half, what is new volume?

  10. Coordinate plane

  11. GOOD LUCK
