Question

find the surface area of cuboid with length 4 cm breath 3 cm and area 1.5

Answer 1

Hey!!!

For a Cuboid, We have
=> l = 4cm
=> b = 3cm
=> h = 1.5cm

Thus Total Surface Area = 2(lb + bh + hl)

=> TSA = 2[(4)(3) + (3)(1.5) + (1.5)(4)]

=> TSA = 2[12 + 4.5 + 6]

=> TSA = 2(22.5)

=> TSA = 45 cm²

Hope this helps
