please see explanation.
Step-by-step explanation:
2268×2=4536
2268×3=6804
2268×4=9072
2268x5=11340
2268×6=13608
2268×7=15876
from the computation 15848 is a perfect square
√15848= 126
to calculate the 126= ✓126=11.225
(5x³-7)(2x²+1)
OPTION D is the correct answer
Number of surface = 5
Surface 1: 8 x 5 = 40 . [The left side]
Surface 2: 15 x 5 = 75 . [The bottom side]
Surface 3: 17 x 5 = 85 . [The slanted side]
[Surface 4 and 5 are triangles and they have the same surface area]
Surface 4 : 1/2 x 15 x 8 = 60
Surface 5 : 60
Total : 40 + 75 + 85 + 60 + 60 = 320 square units
