Answer:

  • surface area: 456 cm²
  • volume: 408 cm³

Step-by-step explanation:

The surface area of the figure is the total of the areas of the two triangular bases and the three rectangular faces.

  SA = 2(1/2)(8 cm)(6 cm) + (17 cm)(6 cm + 8 cm  + 10 cm)

  = 48 cm² + 408 cm²

  SA = 456 cm²

__

The volume is the product of the area of the triangular base and the length of the prism.

  V = (1/2)(8 cm)(6 cm)×(17 cm) = (24 cm²)(17 cm)

  V = 408 cm³

It is true that the product of two consecutive even integers are always one less than the square of their average.

<u>Step-by-step explanation</u>:

Let the two consecutive odd integers be 1 and 3.

  • The product of 1 and 3 is (1\times3)=3
  • The average of 1 and 3 is (1+3)/2 =4/2 = 2
  • The square of their average is (2)² = 4

∴ The product 3 is one less than the square of their average 4.

Let the two consecutive even integers be 2 and 4.

  • The product of 2 and 4 is (2\times4)=8
  • The average of 2 and 4 is (2+4)/2 =6/2 = 3
  • The square of their average is (3)² = 9

∴ The product 8 is one less than the square of their average 9.

Thus, It is true that the product of two consecutive even integers are always one less than the square of their average.
