Question

4
the curved ssurface area
a of a coboid
of dimensions 12.6cm ×7. 5× 5cm is ?​

Answer 1

SOLUTUON :-

• cuboid of dimensions 12.6cm ×7. 5× 5cm is ?
• C.S.A =?
• We know,

★ Curved surface area of cuboid = 2h ( l + b )

Here,

• length = 12.6cm
• breadth = 7.5cm
• height = 5cm

Now,

• keep value in formula •

→ 2h ( l + b )

→ 2 × 5 ( 12.6 + 7.5 )

→ 10 ( 20.1 ) $\bf$

→ 201 cm²

Hence,

Curved surface area of cuboid = 201 cm²

Answer 2

▪ Question -

To Find C S.A of a cuboid having Dimensions - 12.6cm, 7.5cm & 5cm.

▪ Solution -

Here, Let's Suppose the values as -

• Length = 12.6cm

• Breadth = 7.5cm

• Height = 5cm

Now, We Know the Formula for C.S.A of Cuboid -

$\sf{\bold{\boxed{\boxed{\black{2h(l+b)}}}}}$

Placing values as per Given Condition,

$⟹2h(l + b)$

$⟹2 \times 5(12.6 + 7.5)$

$⟹10(20.1)$

$⟹10 \times 20.1$

$⟹201 {cm}^{2}$
