Question

find t.s.a of given cuboid l=10m,b=25m,h=15m​

Answer 1

Answer:

1550m²

Step-by-step explanation:

GIVEN:

length (l)= 10m

breath (b)= 25m

height (h)= 15m

.

To find:

T.S.A of a cuboid= ?

.

T.S.A of a cuboid = 2(lb + bh + hl)

= 2(10×25 + 25×15 + 15×10)

= 2(250 + 375 + 150)

= 2(775)

i.e 2×775

= 1550m²

Therefore, the total surface area of a cuboid is 1550m²
