Question

Find the Volume and/or Surface Area. Use 3.14 for pi. Round answers to the nearest tenths, if necessary.​​​​

Answer 1

7) 42 cm^3

8) 96 cm^3

Explanation:

(Area) Triangle Formula: 1/2(b)(h)

7)

V = 7{1/2(4)(3)}

V = 7{2(3)}

V = 7(6)

V = 42 cm^3

8)

1/2(4)(3)

2(3)

6 (Surface Area of 1 Triangle)

SA = 6(2)+5(7)+3(7)+4(7)

SA = 12+35+21+28

SA = 47+49

SA = 96 cm^3
