Question

Find the TSA and LSA of a cuboid whose length, breadth

and height are 7.5 m, 3 m and 5 m respectively​

Answer 1

Step-by-step explanation:

Lateral Surface area = 2 height(length + breadth

LSA= 2*5(7.5+3)

=10(10.5)

= 105m

SA= 2lw+2hw+2lh

=2*7.5*3+2*5*3+2*7.5*5

=150m

TSA= LSA+SA

= 105+150

= 255m
