The area of a cuboid = 2 (lb + bh + lh) and volume = l*b*h. Find the area and volume of these cuboids. I) l =7 cm, b= 5 cm, h=3 cm
please help me with this question step by step I have to submit it in 10. minutes I will mark you as brainlist

Area = 142 cm^2, Volume = 105 cm^3

BRAINLIEST, PLEASE! (ALMOST AN ACE!)

Step-by-step explanation:

Area: lb + bh + lh

l = 7, b = 5, h = 3

2((7)(5) + (5)(3) + (7)(3))

2(35 + 15 + 21)

2(50 + 21)

2(71)

142 cm^2

Volume: lbh

l = 7, b = 5, h = 3

(7)(5)(3)

35(3)

105 cm^3

Surface area of Cuboid = 2 (lb + bh + lh)

☆l = 7

☆b = 5

☆h = e

Surface area of Cuboid = 2(7*5+5*3 +7*3)

Surface area of Cuboid = 2 (35 + 15 + 21)

Surface area of Cuboid = 2 ( 71 cm³)

Surface area of Cuboid = 142 cm³

⇛Volume of cube = l*b*h

☆l = 7

☆b = 5

☆h = e

⇛Volume of Cube = 7cm*5cm*3cm

⇛Volume of Cube = 105cm³
