Question

find the surface area and volume of a cuboid of length 3m, breadth 2.5m and height 1.5m.​

Answer 1

surface area

2(lb+bl+lh)

= 2(3*2.5+2.5*1.5+1.5*3)

= 2(7.5 + 3.75 + 4.5)

= 2( 15.75)

= 31.5m^2

volume

= lbh

3*2.5*1.5

11.25m^3

Answer 2

Answer:

Explanation:

2[(3*2.5)+(2.5*1.5)+(3*1.5)]

2(7.5+6.25+4.5)

2(18.25)

36.50
