Do you know the formula .Of all questions.....

Answer 2

Step-by-step explanation:

6) (edge)³ = (8)³ = 8×8×8 = 512 cm²

TSA= 6(edge)² =6×(8)³ =384 cm² (for 6 ii just convert meters into cm and follow the same thing like 6 i)

7) =sides³ =216cm³

=> side = ³√216= 6cm (follow same method for 7ii)

8)L= 24cm

B= 18cm

H=4cm

volume of cuboid = l×b×h= 1728cm³

9) It is given that

Length of the wall 900cm

Height of the hall 600cm

Breadth of the wall 20cm

We know that

Volume of the wall 900×600×20cm³= 10800000cm³

Volume of one Brick 30× 15× 10= 4500cm³

So we get

Number of bricks required to construct the wall =

10800000/4500 = 2400
