Perimeter of a triangle

A triangle has the shortest side a=5 cm, the middle side b, and the longest side c=10 cm. A square has a side x=7 cm, which is as long as the side b of the mentioned triangle. A cuboid has a height of 12 cm, a length the same as the longest side of the triangle, and a width of 8 cm. A) determine the perimeter of the triangle. B) is the volume of the cuboid greater than 800 cm3? C) is the perimeter of the square greater than the perimeter of the triangle? D) is the volume of a cube greater than 50 cm3?

Final Answer:

o =  22 cm
V =  960 cm3
o2 =  28 cm

Step-by-step explanation:

a=5 cm c=10 cm x=7 cm b=x=7 cm  o=a+b+c=5+7+10=22 cm
