Answer 1

Answer:

Step-by-step explanation:

A trapezoid and two rectangulars are in the  opening form of the geometric shapes and you should calculate their surface areas seperately which is:

12 cm and 30 cm first rectangular and its surface area is 12 x 30 = 360 cm^2

second rectangular has 30 cm and 26 cm and 30 x 26 = 780 cm^2

A trapezoid surface area is = [(24+29) /2] * 25 = 662.5 cm^2

total surface area = 360 + 780 + 662.5 = 1802.5

Answer 2

Answer:

Total surface area  = 3744 cm^2

Step-by-step explanation:

All linear measurements are in cm

Surface area of BOTH bases

Ab = 2*  (12+29)*24/2

= 984

Circumference of base

Cb = (25+12+26+29)

= 92

Height of prism

H = 30  (given)

Surface area of sides of prism

As= Cb*H

= 2760

Total Surface area of Prism

A = Ab + As

= 984 + 2760

= 3744 cm^2
