Answer:

volume \:  = 3 \times 4 \times 5 \\  = 60 {cm}^{3}  \\ total \: surface \: area = 6 \times 60 = 360 {cm}^{2}  \\ surface \: area \: ofcuboid \:   \\  = 2(3 \times 4 + 4 \times 5 + 5 \times 3) \\  = 2(12 + 2 0+ 15) = 2(47)  \\  =9 4 {cm}^{2}  \\ thank \: u

Hey Mate,

Given Question:-

Find the total surface area of a cuboid edges , 3 cm, 4 cm, 5 cm​.

To Find:-

→ The Total surface Area?

Solution:-

Volume of cuboid = 3cm × 4cm × 5cm

→                                =  60cm³

Total Surface Area = 60 × 6 = 360 cm²

Surface Area of Given Cuboid =

 2 × [ 3 × 4 + 4 × 5 + 5 × 3 ]

→ = 2 × [ 12 + 20 + 15 ] = 94cm²

→ ∴ The Total surface area of cuboid is = 360 : 94

→ = 180 : 47
