Answer:
Total reflective material required = 52 square unit
Step-by-step explanation:
An ice block has the dimensions as 4 units × 2 units × 3 units
This ice block to bee covered with a special reflective paper to protect the ice block from melting.
Amount of reflective material required = Total surface area of the ice block
Since total surface area of a rectangular prism = 2(lb + bh + hl)
Where l = length of the ice block
b = width of the ice block
h = height of the ice block
Now total surface area for the given dimensions = 2(4×2 + 2×3 + 3×4)
= 2(8 + 6 + 12)
= 52 units²
Therefore, total reflective material required will be 52 units².
The total surface area of the cubic ice block will be total reflective material required = 52 square unit
Surface area is the amount of space covering the outside of a three-dimensional shape. Finding surface area
