Question

if r u a genius then prove it by giving the ans of 7,8, and 9 question

Answer 1

Here your answer goes

Question :- 7

Step :- 1

Given , Volume of Cube = 3375^3

Measure of the edge of the cube = $\sqrt[3]{3375} cm$

==> 15 cm

Step :- 2

Total Surface area of a cube = 6 * ( side)^2

( 6 * 15^2 ) cm^2

==>>>( 6 * 225 ) cm^2

1350 cm^2

$\leq \leq \leq \leq \geq \geq \geq$

Question :- 8

Step :- 1

Given dimensions ,

L = 10m

b = 10m

h = 5m

Step :- 2

Diagonal of a cuboid = $\sqrt{l^2 + b^2 + h^2}$

⇒ $\sqrt{(10)^2 +(10)^2 + (5)^2}$

⇒ $\sqrt{100 + 100 + 25 }$

⇒ $\sqrt{225}$

⇒ 15m

Therefore , the length of longest pole is 15m

$\leq \leq \leq \leq \leq \leq \leq \leq \geq \geq \geq \geq$

Question :- 8

Step :- 1

Given ,

length = 12 cm

Breadth = 10cm

Height = ?

Also , Volume = 480 cm^2

Step :- 2

Volume of Cuboid = l * b * h

Evaluate the value

480 = 12 * 10 * H

⇒ $\frac{480}{12 * 10 }$

⇒ $\frac{480}{120}$

⇒ 4

Therefore the height of the cuboid is 4 cm
