Total surface Area of the cuboid is ~

  • [tex] \sf2(lb + bh + lh)[/tex]

  • [tex] \sf2[(12 \times 4) + (4 \times 5) + (12 \times 5)][/tex]

  • [tex] \sf2[48 + 20 + 60][/tex]

  • [tex] \sf2(128)[/tex]

  • [tex] \sf256 \: \: ft {}^{2} [/tex]

solime

Surface area = 256 ft^2

Surface area (SA) = Total area on the Surface only

SA of cuboid = Area of rectangle (2 sides) + Area of square (2 sides) + Area of other rectangle (2 sides)

SA = 2(12x5) + 2(4x5) + 2(12x4)

SA = 120 + 40 + 96

SA = 256 ft^2
