Question

Find the total surface area of this cuboid

Answer 1

Explanation:

☄
`\underline{ \underline{ \sf{Given}}}:`

• Length ( l ) = 4 cm
• Width ( w ) = 2 cm
• Height ( h ) = 5 cm

☄
`\underline{ \underline{ \sf{To \: find}}} :`

• Total surface area of a cuboid

❅
`\underline{ \underline{ \text{Solution}}}:`

✑
`\boxed{ \text{TSA = 2lw + 2lh + 2hw}}`

Plug the known values :

⟼
`\sf{2 * 4 * 2 + 2 * 4 * 5 + 2 * 5 * 2}`

⟼
`\sf{16 + 40 + 20}`

⟼
`\boxed{\sf{76 \: {cm}}^(2) }`

`\red{ \boxed{ \boxed{ \tt{⟿ \: Our \: final \: answer : 76 \: {cm}}^(2) }}}`
