Question

area of cuboid is if its lenght is 15cm nd breadth is 10 cm nd height is 8cm​

Answer 1

Answer:-

$\small \bf \underline{Given:}$

★★ Breadth of the cuboid = 10 cm

★★ Length of the cuboid = 15 cm

★★ Height of the cuboid = 8 cm

$\small \bf \underline{To \: find:}$

We need to find the surface area of the cuboid

$\small \bf \underline{Solution:}$

» Formula to find the surface area of the cuboid =

$\small\bf \: 2(length \times breadth + breadth \times height\\ \bf + \: height \times length)$

$\bf = 2(15 \times 10 + 10 \times 8 + 8 \times 15)$

$\bf = 2(150 + 80 + 120)$

$\bf = 2 \times 350$

$\bf = 700 \: {cm}^{2}$

Therefore, the surface area of the cuboid is 700 cm²

Answer 2

Answer:

given:★★ Breadth of the cuboid = 10 cm

★★ Length of the cuboid = 15 cm

★★ Height of the cuboid = 8 cm

\small \bf \underline{To \: find:}

We need to find the surface area of the cuboid

\small \bf \underline{Solution:}

Solution:

» Formula to find the surface area of the cuboid =

\begin{gathered} \small\bf \: 2(length \times breadth + breadth \times height\\ \bf + \: height \times length)\end{gathered}

2(length×breadth+breadth×height

+height×length)

\bf = 2(15 \times 10 + 10 \times 8 + 8 \times 15)=2(15×10+10×8+8×15)

\bf = 2(150 + 80 + 120)=2(150+80+120)

\bf = 2 \times 350=2×350

\bf = 700 \: {cm}^{2}=700cm

2

Therefore, the surface area of the cuboid is 700 cm²
