Answer:
S.A of a rectangular prism is 2lh+2lw+2hw
2(4x6)+2(4×4)+2(6×4)
2(24)+2(16)+2(24)
48+32+48= 128cm²
Step-by-step explanation:
Number of sides of the given polygon, n =5
Sum of interior angles =( n-2)180°
=( 5 - 2)180°
= 3*180°
= 540°
Missing angle, x = 540°- (100°+105°+110°+145°)
= 540°- 460°
= 80°
