Here's some required measures !

  • 1 ft = 12 inches

  • 0.4 ft = 0.5 × 12 = 6 inches

Let's calculate its surface area ~

  • [tex] \sf2[(12 \times 10) + (11 \times 12) + (10 \times 11) ] - 2(7 \times 7) [/tex]

  • [tex] \sf2[120 + 132 + 110 ] - 2(49) [/tex]

  • [tex] \sf{2(362)} - 98[/tex]

  • [tex] \sf724 - 98[/tex]

  • [tex]6 \sf26 \: \: in {}^{2} [/tex]
