Question

Find the width of a rectangular prism with a surface area of 250 square cm, a height of 5 cm, and a length of 10 cm. 15 cm 50 cm 5 cm 25 cm

Answer 1

Let, the width = w

We know, A = 2(lw + wh +hl )
250 = 2(10w + 5w + 50)
250 = 2(15w + 50)
250 = 30w + 100
30w = 250 - 100
w = 150/30
w = 5

In short, Your Answer would be Option C) 5 cm

Hope this helps!
