The surface area of a rectangular prism needs an formula.
For a rectangular prism you have to understand some about the shape.
It is a 3D shape consisting of 6 sides
all are rectangles
to determine the area of one rectangle is the base multiplied by the height or in this case length times with.
but you also need to account for all sides and the height.
so the Surface area formula would be like
sa = l \times w + l \times h + w \times h
this accounts for 3 of the sides of the rectangular prism.
the top,bottom,and side.
so to get the surface area of a rectangle prism you must mutiply each side by 2 to account for all sides of the rectangular prism.
so the surface area formula for a rectangular prism is
SA = 2\\  \times l \times w +2 \times l \times h+2 \times h \times w
I won't solve it for you but just plug in your values for l,w,and h into that formula and you will get your answer in metres squared or m

Give an example for a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles
cluponka [151]

Answer:

One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles.

Step-by-step explanation:

so if I was you I would use that strategy to try to find the pair of the Alternate exterior angles.

so the agles are probably 1 and 7 but i don’t want you to get it wrong so here’s a picture Of an example.

If sin theta = -0.7660, which of the following represents an approximate value of tan theta, for 180 degrees < theta < 270
Elis [28]
We have that
sin ∅=-0.7660

the sin ∅ is negative
so 
∅ belong to the III or IV quadrant
but
180°< ∅ < 270°
hence
∅ belong to the III quadrant
sin ∅=-0.7660
sin² ∅+cos² ∅=1
cos² ∅=1-sin² ∅------> cos² ∅=1-(0.7660)²-----> 0.4132
cos ∅=√0.4132-----> cos ∅=0.6428
the value of cos ∅ is negative-------> III quadrant
cos ∅=-0.6428

tan ∅=sin ∅/ cos ∅----> tan ∅=-0.7660/-0.6428----> tan ∅=1.1917

the answer is
tan ∅ is 1.1917

Readme [11.4K]

Answer:

1/7

Step-by-step explanation:

They traveled 5/7 of the distance on Saturday.

That left 2/7 of the distance as the remaining distance.

They traveled half of 2/7 of the distance on Sunday.

1/2 of 2/7 = 1/2 × 2/7 = 2/14 = 1/7

Answer: 1/7
