Question

EXERC y Short Answer Type Questions Find the surface area of a box whose length is 40 c breadth 27 cm and height 10 cm.​

Answer 1

Answer:

Surface Areas And Volumes- The chapter begins with recalling plane and solid figures. The chapter explains that how the relationship between length and breadth of the figure can give us area and inclusion of the concept of heights can provide us the volume of any particular given object.

The first section is about the surface area of a cuboid and a cube. This includes lateral surface area of a cuboid as well.

Answer 2

Answer:

The surface area of a box is 3520cm^2.3520cm

.

Step-by-step explanation:

Given,

Length(l) = 40cm, breadth(b) = 27cm and height(h) = 10cm

To find, the surface area of a box = ?

We know that,

The surface area of a box = 2(lb+bh+hl)=2(lb+bh+hl)

= 2(40\times 27 + 27 \times 10 + 10 \times 40 )=2(40×27+27×10+10×40)

= 2(1080+270+400) cm^{2}=2(1080+270+400)cm

2

= 2\times 1750 cm^{2}=2×1750cm

2

= 3520cm^2=3520cm

2

Hence, the surface area of a box is 3520cm^2.3520cm
