Three same-sized cubes are attached to the top of a rectangular prism as shown below.
If a=10 cm, b = 26 cm, and c = 6 cm, what is the surface area of the figure?
ANSWER ASAP PLEASE!!! IT WOULD MEAN ALOT

Answers

Answer:

Surface area of the figure = 1672 [tex]cm^{2}[/tex]

Step-by-step explanation:

Surface area of the figure = surface area of the prism + surface area of the 3 cubes

The surface area of the rectangular prism = sum of the area of its individual sides

                                             = 2(26 x 10) + 2(10 x 10) + 2(26 x 10)

                                             = 520 + 200 + 520

The surface area of the rectangular prism = 1240 [tex]cm^{2}[/tex]

Surface area of one of the cubes = 5(6 x 6)

                                                      = 180 [tex]cm^{2}[/tex]

The surface area of the 3 cubes = 3 x 180

                                                     = 540 [tex]cm^{2}[/tex]

Thus, the surfaces of the cubes on the prism covers a total area of 108 [tex]cm^{2}[/tex].

So that;

The surface area of the figure = (1240 - 108) + 540

                                               = 1132 + 540

                                                = 1672 [tex]cm^{2}[/tex]

A rod 123.75 cm long is sawn into 16 equal lengths. If a wastage takes place of ¼ cm for each saw cut, what is the length of each piece?

Answers

Answer:

7.5 cm

Step-by-step explanation:

A rod 123.75 cm long is sawn into 16 equal lengths.

The length of each rod is calculated as:

123.75cm/16 =

= 7.734375cm

If a wastage takes place of ¼ cm for each saw cut,

The length of each piece is calculated as:

7.734375cm - 1/4 cm

7.734375cm − 0.25 cm

7.484375cm

Approximately = 7.5 cm

Therefore, the length of each piece = 7.5 cm

if h(x)=x-7 and g(x)= x^2, which expression is equivalent to (goh)(5)

Answers

Answer:

(goh)(5) = 4

Step-by-step explanation:

(goh)(x) = g(x-7)

g(x-7) = (x-7)^2

g(x-7)= x^2 - 14x + 49

(goh) = x^2 - 14x + 49

(goh)(5) = 5^2 - 14(5) + 49

(goh)(5) = 25 - 70 + 49

(goh)(5) = 4
