Question

find the lateral surface area of cuboid whose length is twice the breadth ​

Answer 1

Answer:

L length of a cuboid is twice its breadth the breadth is twice its height ...

LSA OF CUBOID =2(l+b)h

2(20+10)40

=2400squnits

TSA OF CUBOID =2(lb+bh+lh)

2(20×10+10×40+40×20)

=2800squnits

4.3

Answer 2

Answer:

Step-by-step explanation:

   LET THE VALUE OF THE LENGTH AND BREATH 2X AND X RESPECTIVELY .

LET THE VALUE OF THE HEIGHT BE Y$2{X}*{Y}+ {X*}{Y}$

   THE LSA OF A CUBOID= 2(LH+BH)

                                          = 2($2{X}*{Y}+ {X*}{Y}$)

                                          =2(2XY+XY)

                                           =2(3XY)

                                           =6XY
