Answer:

x = 41    ||      surface area = 8950 cm³

Step-by-step explanation:

1)

[tex]c^{2}=u^{2}+z^{2}- \frac{6x}{y+4u}[/tex]

[tex]-u^{2}-z^{2}+c^{2}=- \frac{6x}{y+4u}[/tex]

[tex]+u^{2}+z^{2}-c^{2}=\frac{6x}{y+4u}[/tex]

[tex]({y+4u})(+u^{2}+z^{2}-c^{2})={6x}[/tex]

[tex]\frac{({y+4u})(+u^{2}+z^{2}-c^{2})}{6} =x[/tex]

[tex]x =\frac{(10+4(-1))((-1)^{2}+7^{2}-(-3)^{2} ) }{6}[/tex]

[tex]x=41[/tex]

2)

Formula of surface area of cuboid:

2(lh + lw+ hw) square units

2(60*25+60*35+25*35)

2(4475)

8950 cm³
