Hello,
I am going to calculate all the surface areas of the prism:
1) the bases: 2*(6*9)/2=64 (cm²)
2) perimeter of the base: 7+9+7=23 (cm)
3 lateral area: 23*5=115 (cm²)
All surface areas= 64+115=179 (cm²)
What does it means sq ? (for a foreigner) ?
All surface areas= 64+115=179 (cm²)
What is triangular prisms?
A three-sided polyhedron consisting of a triangle base, a translated copy, and three faces connecting equivalent sides is known as a triangular prism in geometry. If the sides of a right triangular prism are not rectangular, the prism is oblique.
Given
