Answer:
C
Step-by-step explanation:
The answer would be: 67.89 x 10^6
The rules of significant numbers used:
- any non-zero digit is significant
- zeroes that are in the right side of the non-zero whole number would not be significant
Thus, only the significant numbers left in the equation:
67.89 x 10^6
10099 is this right i think it would be
Answer: Surface area = 46 units²
Step-by-step explanation:
The formula for determining the total surface area of a rectangular prism is expressed as
Surface area = 2LW + 2LH + 2WH
Where
L represents the length of the rectangular prism.
W represents the width of the rectangular prism.
H represents the height of the rectangular prism.
Looking at the diagram,
L = 4 units
W = 2.5 units
H = 2 units
Therefore,
Surface area = (2 × 4 × 2.5) + (2 × 4 × 2) + (2 × 2.5 × 2)
= 20 + 16 + 10
= 46 units²
