Question

find the surface area of a cuboid where length is equal to 5 cm breadth is equal to 4 cm height is equal to 3 cm​

Answer 1

Total surface area of cuboid = 2(lb + bh + hl)

l = 5 , b = 4 , h = 3

∴ TSA = 2(20 + 12 + 15)

          = 2(47)

          = 94cm²

Answer 2

Answer:

94 cm²

Step-by-step explanation:

Length (l) = 5 cm

Breadth (b) = 4 cm

Height (h) = 3 cm

S.A or TSA = 2(lb + bh + hl) = 2((5)(4) + (4)(3) + (3)(5)) = 2(20 + 12 + 15) = 2(47) = 94 cm²
