Question

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

Answer 1

Answer:

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

Answer 2

→ 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
