Answer:
- 132
Step-by-step explanation:
This can be evaluated without a calculator.
Take each part of the calculation and evaluate, that is
- 6(3)(- 4) = - 6 × - 12 = 72
3(3)²(- 4) = 3 × 9 × - 4 = - 12 × 9 = - 108
2(3)(- 4)² = 6 × 16 = 96
Putting the 3 parts back together
72 - 108 - 96
= 72 - 204
= - 132
Answer:12
Step-by-step explanation: 0.6 x 20= 12
Total area of the ends: 2(2")(6") = 24 in^2
Total area of the sides: 2(2")(9") = 36 in^2
Are of the bottom : 1(6")(9") = 54 in^2
Total surface area to be covered = (24+36+54) in^2
