Question

If length of a cuboid is 10cm ,breadth is 4 cm and height is 8cm. Find its vertical surface area.​

Answer 1

Answer:-

Given,

Length=10cm.

Breadth=4cm.

Height=8cm.

Vertical Surface Area

=2*h(l+b)

$\sf = 2 \times 8 \times (10 + 4) {cm}^{2}$

$\sf = 16\times 14 {cm}^{2}$

$\sf = 224{cm}^{2}$

Hence, the vertical surface area=224cm².

Answer 2

Answer:

2h(l+b)

=2×8(10+4)=16×14=224 cm^2.
