Question

Find the TSA, LSA of a cuboid of side length 13cm​

Answer 1

Answer:

You can't find the cuboids TSA and LSA by only Length.

Post full details.

But the formula for TSA = 2(lb+bh+lh)

and the formula for LSA = 2h(l+b)

Hope it helps.

Answer 2

$\sf{\huge{\underline{\pink{Answer :-}}}}$

Given :-

• A cuboid of side length 13cm .

To Find :-

• The TSA of a cuboid.

• The LSA of a cuboid.

Formulae to be Used :-

• 2 ( lb + bh + hl )

• 2 h (l+b)

Solution :-

We, are given only length = 13 cm

So, let the breadth be b cm.

& the hieght = h cm.

• The total surface area of a cuboid is 2 ( lb + bh + hl ) .

➝ 2 (13×b + bh + 13h)

➝ 2 ( 13b + bh + 13h )

➝ ( 26b + bh + 26h )

-----------------------------------------------------------------

• The lateral surface area of a cuboid is 2 h (l+b) .

➝ 2 h ( 13 + b)

➝ (26h + 2bh)
