please i will give brainliest if right

Answer 1

Answer:

s = 156.25 square meters

Step-by-step explanation:

s = 2lw + 2lh + 2wh

s = 2(5.5)(3) + 2(3)(7.25) + 2(5.5)(7.25)

s = 33 + 43.5 + 79.75

s = 156.25 square meters

Answer 2

Answer:

We know,

$\quad$${\boxed{ \rm{Surface \: Area_{ \: (rectangular \: prism)} = 2(lb + bh + hl)}}}$

where,

• Height (h) = 7.25m
• Breadth (b) = 3m
• Length (l) = 5.5m

$\:$

${\longrightarrow { 2 ( 5.5 \times 3 + 3 \times 7.25 + 7.25 \times 5.5 ) }}$

$\longrightarrow$ 2 ( 16.5 + 21.75 + 39.875 )

$\longrightarrow$ 2 ( 78.125 )

$\longrightarrow$ 156.25

Thus, The Surface Area of rectangular prism is 156.25cm².
