Question

find the T.S.A of a cuboid of measures 20cm x 10cm x 15cm​

Answer 1

multiply those all u will get ur answer nd ur answer is 3000

Answer 2

Given :-

• Length = 20cm
• Breadth = 10cm
• Height = 15cm

To find :-

• Total surface of area of cuboid

Solution :-

Required Formula :

$TSA = 2(lb + bh + lh)$

We have,

Length =20cm

Breadth =10cm

Height =15cm

Putting value

$TSA = 2(20 \times 10 + 10 \times 15 + 20 \times 15) \\ TSA = 2(200 + 150 + 300) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ TSA = 2(650) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ TSA = 1300 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

TSA is 1300cm²
