Question

tsa of cuboid is 30cm 25 cm and 25 cm.​

Answer 1

TSA OF CUBOID = 2(LB + BH+HL)

2(30×25+25×25+25×30)

2(750+625+750)

2(2125)

= 4250 CM²

Q

Answer 2

Correct Question :-

• Find the TSA of a cuboid having the Dimensions 30 x 25 x 25 cm.

Answer :-

• TSA of cuboid = 4250 cm²

Given :-

• Length of cuboid = 30 cm
• Breadth of cuboid = 25 cm
• Height of cuboid = 25 cm

To Find :-

• TSA of Cuboid = ?

Explanation :-

As we know, Total Surface Area of Cuboid means Area of all Six faces of the cuboid.

$\rm \implies \bold { TSA \: of \: Cuboid = 2(LB + BH + HL) \; cm^2}$

Now, substituting the values

$\rm \implies 2[(30 \times 25) + (25 \times 25) + (25 \times 30)] \: cm^2$

$\rm \implies 2 (750 + 625 + 750) \: cm^2$

$\rm \implies 2 (2125) \: cm^2$

$\rm \underline { \boxed { \implies \bold { 4250 \: cm^2 }}}$

Hence, the TSA of cuboid is 4250 cm²
