What is the surface area of the prism? A rectangular prism with a length of 3 meters, width of 4 meters, and height of 2 meters.

Naddik [55]

Answer:

52m²

Step-by-step explanation:

For this you would consider each face of the figure as a rectangle, and then multiply it by two.

Face 1:

3m×4m×2=24m²

Face 2:

4m×2m×2=16m²

Face 3:

3m×2m×2=12m²

Then you add each of them together to get the overall surface area

12m²+16m²+24m²=52m²

Therefore the final surface area is 52m²

Find the measures of the four numbered angles

Genrish500 [490]

First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65

Explain please and tell me how to do it ?

SCORPION-xisa [38]

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.

Total area = area of square + area of rectangle + area of triangle

= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)

= (9 + 32 + 7.5) cm^2

= 48.5 cm^2 (total area of figure)
