Question

Find the total surface area of the cuboid of dimensions 5 cm X 3 cm X 2 cm is

​

Answer 1

Answer:

TSA = 62 sq. cm

Step-by-step explanation:

let l=5cm

    b=3cm

    h=2cm

Since TSA of Cuboid =2(lb+bh+lh)

Therefore

TSA =2(5*3 + 3*2 + 2*5)

         =2(15 + 6 + 10)

         =2(31)

         =62 sq. cm

Answer 2

$\huge \underline{ \underline{ \bf \purple{Solution :}}}$

TSA of cuboid = 2 ( LB + BH + HL )

⇒ TSA = 2 ( 5 × 3 + 3 × 2 + 2 × 5 )

⇒ TSA = 2 ( 15 + 6 + 10 )

⇒ TSA = 2 ( 31 )

⇒ TSA = 62 cm²
