some help and give awnser 50 points I beg u help meneed 5 and 9 surface area and volume

Question 5:

[tex]\text {Surface Area = } 2( \frac{1}{2} \times 4 \times 4) + (4 + 4 + \sqrt{4^2 +4^2}) \times 8 = 125.6 \text{ yd}^2[/tex]

[tex]\text{Volume = } \frac{1}{2} \times 4 \times 4 \times 8 = 64 \text { yd}^3 [/tex]

Question 9:

[tex]\text {Surface Area = } 2( \frac{1}{2} \times 3 \times 7) + (3 + 7 + \sqrt{3^2 +7^2}) \times 6 = 126.6 \text{ mm}^2 [/tex]

[tex]\text{Volume = } \frac{1}{2} \times 3 \times 7 \times 6 = 63 \text { mm}^3 [/tex]
