Solution:

Note that:

  • Surface area: 2(LB) + 2(BH) + 2(LH)

Substitute the values given into the expression to find the surface area.

  • 2(7 x 10) + 2(6 x 6) + 2(6 x 10)
  • => 2(70) + 2(36) + 2(60)
  • => 140 + 72 + 120
  • => 332 mm²

The surface area of the rectangular prism is 332 mm².

Length = 6 mm

Height = 7 mm

Width = 10 mm

We know that,

[tex] \boxed{\rm Surface\:area\:of\:rectangle=2(LB)+2(BH)+2(HL)}[/tex]

  • Plug in the given values!~

[tex] \sf \nrightarrow \: SA = 2 \times (6 \times 10) + 2 \times (7 \times 10) + 2 \times (6 \times 7)[/tex]

[tex] \sf \nrightarrow \: SA = 2 \times 60 + 2 \times 70 + 2 \times 42[/tex]

[tex] \sf \nrightarrow \: SA = 120 + 140 + 84[/tex]

[tex] \tt \multimap \: SA = 344 \: {mm}^{2} [/tex]
