Question

3. If perimeter of base of a cuboid is 24 cm and whose
lateral surface area is 216 cm- then height of cuboid
is
(1) 192 cm
(2) 19.2 cm
(3) 0.9 cm
4). 9 cm​

Answer 1

Answer:

d part

pls mark as brainliest and also do thanks

Answer 2

Answer:

let length of the cuboid be x and breadth be y and height be z

according to problem,

perimeter of cuboid equal to 24 which means x+y= 12

lateral surface area is 2h (l+b) =216 i.e. 2h(x+y)=216

2h (12)=216 i.e. 2h = 216/12

therefore h=18/2=9
