Answer: Surface area = 392 in²

Step-by-step explanation:

It is divided into different sections as shown in the attached photo to aid explanation.

Looking at the attached photo

Area of A = 6 × 6 = 36 in²

Area of B = 4 × 10 = 40 in²

Area of the face containing A and B = 36 + 40 = 76 in²

Since the face is the same on the opposite end,

Area of the opposite end of AB = 76 in²

Area o C = 6 × 4 = 24 in²

Area of D = 6 × 6 = 36 in²

Area of E = 6 × 6 = 36 in²

Area of F = 6 × 4 = 24 in²

Area of base G = 10 × 6 = 60 in²

Area of back H = 6 × 10 = 60 in²

The surface area is the sum of all the faces of the given solid.

Therefore,

Surface area = 76 + 76 + 24 + 36 + 36 + 24 + 60 + 60 = 392 square inches

Lena [83]

Answer:

The equation of line which is parallel to the given line is y =  3 x + k.

Step-by-step explanation:

The equation of the line is

y = 3 x - 8

Compare with the standard equation

y = mx + c

The slope of line is

m = 3

So, the line parallel to the given line is

y = 3 x + k

where, k is any real number.

Last month Hao dog ate 40 cans of dog food in 31 days. How many cans should Hao buy to feed his for for the next 6 days?
Furkat [3]

we are given

Hao dog ate 40 cans of dog food in 31 days

it means that

31 days =40 cans

Firstly, we will find for 1 day

we can divide both sides by 31

\frac{31}{31} day=\frac{40}{31} cans

1 day=\frac{40}{31} cans

now, we can multiply both sides by 6

6*1 day=6*\frac{40}{31} cans

6days=7.74194 cans

so,

Hao buy to feed his dog  for for the next 6 days is 7.74194 cans.......Answer
