Answer 1

Tin boxes*
L=16 cm
B=12cm
H=8 cm
Area of one tin box= lxbxh
16*12*8
=1536 cm^2
Area of 10 tin boxes=1536x10
=153600cm^2
In meters=153600/100
=1536 m^2

Answer 2

Answer:

8320 $cm^{2}$

Step-by-step explanation:

Tin sheet with 3 dimensions means it is a cuboid made from a net; a net is basically a blueprint for a shape which needs to be folded appropriately to make the shape  

In the case of a cuboid with no same dimension; all 3 are different we can make the shape by 6 rectangles we will use the surface area formula here

2lw+2lh+2hw

We will now input the values

L = 16

H = 12

W = 8

2(16 x 8) + 2(16 x 12) + 2(12 x 8)

Which would give us….

832 $cm^{2}$

This is for 1 box  

We must multiply this by 10

Thus the answer will be 8320 $cm^{2}$
