They add up to: (3*7)+(5*5) = 46 sides
A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides altogether.
A triangle has 3 sides, so 5 triangles have a total of 5 x 3 = 15 sides. A pentagon has 5 sides, so 3 pentagons have a total of 3 x 5 = 15 sides. Adding these together, 15 sides from triangles and 15 sides from pentagons gives a total of 15 + 15 = 30 sides.
There are: (5*6)+(3*5)+(5*3) = 60 sides
A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether
All pentagons are 5 sided polygons
74 sides
heptagons have 7 sides pentagons have 5 sides therefore 4 x 7 = 28 4 x 5 = 20 Total 48 sides.
A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides altogether.
Three pentagons have a total of 15 sides. Each pentagon has 5 sides, so when you have 3 pentagons, you would multiply 5 sides by 3 pentagons to get 15 sides in total.
A triangle has 3 sides, so 5 triangles have a total of 5 x 3 = 15 sides. A pentagon has 5 sides, so 3 pentagons have a total of 3 x 5 = 15 sides. Adding these together, 15 sides from triangles and 15 sides from pentagons gives a total of 15 + 15 = 30 sides.
There are: (5*6)+(3*5)+(5*3) = 60 sides
A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether
Not if they are regular 5 sided pentagons
All pentagons are 5 sided polygons
A decagon has 10 sides, a dodecagon 12, and a pentagon 5. So 4 decagons, 5 dodecagons, and 3 pentagons have 4*10 + 5*12 + 3*5 sides = 40 + 60 + 15 = 115 sides altogether.
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
They are plane faces which can have from 3 to 5 sides (triangles, quadrilaterals and pentagons)..
