Answer 1

Question :

find the total area of the cuboids of length breadth and height as given below: give answer by steps 4m,2.5m,1.5 m ܝܢ

Answer :

$\sf\pink{given}$

• length = 4 m

• Breadth = 2.5 m

• height = 1.5 m

Explanation :

Total Surface Area of Cuboid = 2(lb + bh + hl )

$\longrightarrow\bf{2\times (4\times 2.5 + 2.5\times 1.5 + 1.5\times 4)}$

$\longrightarrow\bf{2\times (10 + 3.75 + 6 )}$

$\longrightarrow\bf{2\times 19.75}$

$\longrightarrow\bf{39.5}$

• Therefore the total surface area is 39.5 m²

Answer 2

Answer:

39.5cm³

Step-by-step explanation:

length (l) = 4cm

breadth (b) = 2.5cm

height (h) = 1.5

Surface area of cuboid = 2( lb+bh+hl)

= 2(4×2.5+2.5×1.5+1.5×4)

= 2(10+3.75+6)

= 2(16+3.75)

= 2×19.75

= 39.5cm³
