Find the surface area of the prism.

Brrunno [24]

Answer:

108 cm²

Step-by-step explanation:

the surface area is the sum of all individual shapes areas on the surface.

2 right-angled triangles

3 rectangles

area of a right-angled triangle is At = a×b/2

At = 4×3/2 = 6 cm²

we need it twice : 12 cm²

one rectangle (length×width) = 8×3 = 24 cm²

one rectangle = 8×4 = 32 in²

one rectangle = 8×5 = 40 cm²

total surface area

A = 12+24+32+40 = 108 cm²

an area is always a square unit (power of 2).

a volume is always a cubic unit (power of 3).

and a length is always a simple unit (power of 1).

Answer:

Here's your solution

=> Both angles are interior angles hence their

=> sum will equal to 180°

 => (2x + 10)° + ( x + 5) = 180°

=> 2x + 10° + x + 5° = 180°

=>.3x + 15° = 180°

=> 3x = 180° - 15°

=>. 3x = 165°

=>. x = 165/3

=>. x = 55°

=> hence angle = 120° and 60°

hope it helps
