Answer:

volume is l×b×h.

thats 16*12*5 that is 960cm cubed.

total surface area is 2(l×b+b×h+h×l).

that's 2(16×12+12×5+16×5).

664 cm squared .

Answer:

surface area=2(lb+bh+hl)

surface area=2(16×12+12×5+5×16)

surface area=664cm²

volume = 16cm×12cm×5cm

volume= 960cm³

Find the sine, cosine, and tangent of 45 degrees.
frosja888 [35]

Answer:

The correct answer is option C.

Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1

Step-by-step explanation:

The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.

The table is easily available on the internet.

WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.

The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.

So

Sin 45 = √2/2

Cos 45 = √2/2

and

Tan 45 = 1

So the correct option is C.

Nine more than the product of 22 and Gordons height​
OverLord2011 [107]

Answer:

9 + 22h

Explanation:

The question is incomplete as Gordon's height is not given. To solve further, we will represent this height with h

So, we have:

nine more than the product of 22 and Gordons\ height

More than, in this case means plus (+)

nine + the product of 22 and Gordons\ height

Rewrite nine as 9 and substitute h for Gordons height

9 + the product of 22 and h

product, in this case means multiplication (*)

9 + 22 * h

So, the expression is:

9 + 22h
