Question

find the total surface area of the cuboid of length 8m,breadth 5m and height 3.5​

Answer 1

Answer:

total surface area of cubiod= 2(lb+bh+lh )

so l=8m

b=5m

h=3.5m

A/Q 2(8×5+ 5×3.5+ 3.5×8)Sq.m

= 2 (40+ 17.5+28)Sq.m

= 2×86.5 Sq.m

= 173.0 Sq.m

hope it help you.

please mark me in brain list.

Answer 2

Step-by-step explanation:

TSA= 2(lb +bh+hl)

l = 8m

b = 5m

h = 3.5m

... then A/Q. = 2(8×5+5×3.5+3.5×8)

= 2(40+17.5+28)

=171.0 m×m

..., hope fully .. your doubt was clear
