Question

Ons 3. The dimensions of a metallic cuboid
ve 100 cm X 270 cm X 125 cm
It ir
melted and recast into a cube.. finds
The edge of the tube Cube
dili The total surface area of the cube.
& The edge.​

Answer 1

Answer:

$\huge\red{\underline{\mathbb{Answer:-}}}$

(i) Edge of the cube = 150 cm^2

(ii) Total surface area of cube = 13500 cm^2

$\huge\red{\underline{\mathbb{Explanation:-}}}$

When the cuboid is melting into cube volume remain same.

Volume of cuboid = Volume of cube

l × b× h = s^2

100 × 270 × 125 = s^2

s^2 = 337500

Taking cube root

s = 150 cm

Now,

Total surface area of cube is

TSA = 6×s^2

TSA =6×150^2

TSA = 135000 cm^2

l hope It's help u...
