140 cm^2

Step-by-step explanation:

each lateral = 5×7 = 35 cm^2

there are 4 lateral,

so total area = 4×35 = 140 cm^2

Answer: 140cm2

Step-by-step explanation:

The base and top are not included in the lateral area so all the other faces have the same surface area which is 7x5=35cm2. Now multiply this by four sides which is 35x4=140cm2.
