Question

hi guys please answer the questions who gives me frist I give brainliest ok but correct answer so I give brainliest so ok but all ok byy​

Answer 1

given side of cube,a =2cm

formula to find surface area of cube is 6a²

substituting the value v get 6×2²=6×4=24cm²

given length,l =6 breadth,b =3 height ,h=1

formula to find volume of cuboid=l×b×h

on substituting we get 6×3×1=18cm³

given radius of cylinder=14cm and height =5cm

formula to find volume of cylinder =

$\pi {r}^{2} h$

=22/7×14×14×5=3080cm³
