Answer: It wants you to find the "Lateral Surface Area" or as I call it the area of the dimensional figures sides.
Step-by-step explanation:
If you times 24 by 48 then you get 1,152. 3 times 24 is 72. You would then subtract 1,152 by 72 which equals 1,080 postcards left is what the shop has to sell.

Answer:
A = 94.2 cm²
Step-by-step explanation:
Given that,
Length, l = 5 cm
Width, b = 2 cm
Height, h = 5.3 cm
We need to find the surface area of the solid cuboid.
The formula for the surface area of the sold cubiod is given by :
A = 2(lb+bh+hl)
Substitute the values in the above formu;a
A = 2(5(2)+2(5.3)+(5.3)(5))
= 2(10+10.6+26.5)
= 2(47.1)
= 94.2 cm²
Hence, the required surface area is 94.2 cm².
